Does Pilosoft then not charge for additional IP's?  If so, can't get  
at least a /8 from you if I buy a Pilosoft DSL line, how about just  
a /24 for starters?

I'll use every single address immediately.

But aren't there costs managing the individual IPv4 addresses?  I ran  
a web-hosting ISP, you run a full-blown ISP- doesn't someone have to  
get paid to manage netblock usage, as a part of managing the  
service?  Doesn't that task become more time consuming (and  
difficult) as netblocks become more completely utilized?

Awesome- can you point me at any historical references?  This is the  
fun stuff I love...

Are you referring to NCP transitioning?

Again, where is my free /24 for my home?  I'll use every one, right now.

Gotcha- who are the providers who do both v4 and v6?

Is scenario perhaps influenced because you moderate the Nanog list?  :)

End to end connectivity between machines, making more devices  
available over the internet.
(I have many small networked systems in my home office I'm dying to  
have online TODAY.)

Wouldn't you'd sell more bandwidth, if more people used more internet  
services and devices?

Home Style Answer:
Easy, personally, counting on my hands (the geek view):

I just counted 19 computers of various shapes and sizes,  
architectures- in my home office, which I use and would quickly  
connect to the internet.  Of those 18 computers, 6 of them have 2 or  
more ethernet interfaces, and I count 9 wireless interfaces.  I'm  
doing dev. work using jails, and working on jailed system  
architecture.  My apartment alone currently has 3 active /24 subnets,  
all NAT'd behind 2 public IP addresses, and only a few machines have  
services I'd want to keep local-only...
The rest, are actually would be REALLY valuable to me if they were  
publicly available- (and people I'm working with for personal, work,  
and open-source dev. projects)  This is just the stuff that I see out  
and around my office, some of it is noisy old stuff and only gets  
turned on periodically.

Got all the numbers there?  Sounds like any of our geeky home/office  
arrangements, right?

Not to mention that I'd love some IP space to use IP telephony (and  
video stuff), as well as room to simply experiment with the network/ 
netblocks itself...
We all do this on our LAN's, but it's more valuable to me to get the  
systems online!

I don't know how many machines I've got running, and this isn't NASA  
or anything here- lots of crappy machines- in an apartment, being  
routed with PC gear, but I'm truly not kidding when I say I could use  
65k IP's.

Work Style Answer:

Here's my current business need (growing in recent months, not  
I work for people doing business in China, Taiwan, Japan- and they're  
spreading sales and operations into Europe.  I won't mention the  
client, but I'll say that moving files around between the businesses  
is a huge part of their income- loads of multimedia, various web-apps  
and file servers for industrial manufacture and multimedia  
production, etc... (this is why I work for them, managing and  
building applications and networks).

So, with that stated, their customers in Asia, (mostly other  
businesses, not direct consumers), are increasingly mentioning  
services on corporate IPv6 networks, and they maintain a few IPv4  
points of entry into their network which Americans/Westerners touch.   
The servers they maintain on the IPv4 internet are saturated.  With  
that, it would actually be FAR more convenient if we all could simply  
connect to their servers via IPv6, and provide them usable IPv6  
service as well.

There's loads of confusion about IT from my employers, because  
there's enough difficulty with spoken language barriers...

Another business client is starting to sell products across the  
internet in Japan, and gee-whiz, do I have to go to Japan and get a  
cabinet to make this happen?  (oh twist my arm, right...)

One other incentive for me right now- you know how much money I make  
on all this IPv6 related work?  Right now, ZERO.  I have no IP's or  
pipe to work with.
But out of a desire to grow, I'm willing to invest the time and  
resources to make more (and more interesting) work for myself...   
E.G. it's worth the expenditure, based on interest, and trust in  
future returns.

So is that enough of a business case for me ask my ISP's for a  
production-grade IPv6 internet connection?

I appreciate this info Alex, it puts a lot into perspective for  
American networks.

Neither is v4, it could be argued :)

It seems in America, no ISP seems to.

We're talking about separate business cases,

+ YOUR business case. (selling/providing IPv6)
+ MY business case. (acquiring/deploying IPv6)

What follows is meant with a great deal of respect, but none the  
less, it's a challenge:

Your business case (as the ISP) is a serious and challenge, but an  
old one- an upgrade.  We all know upgrades are painful transitions,  
so much respect is due any ISP.
Yet I don't see anything but frustrated excuses for "why nobody  
cares", yet you (and most network operators) are resident experts on  
the topic(?).  How are ISP's and network operators so expert in  
something they don't care about enough to use, or deploy?
How do you know the challenges before you do it?  I'm not saying it's  
not a risk, it sure as hell is- but realistically, that's where the  
'business case' is.  Whoever takes the risk, makes the money- (or  
perhaps looses it).

I'm simply getting tired of getting more finger-pointing up the chain  
from ISP's.
Backbone providers are never going to initiate v6-native-capable  
links, they have no/little need- they don't make money off the  
endpoints en'-masse.

I'm interested in hearing from ISP's who say 'we did something, come  
buy some', even if it's just spit-and-glue tunnels...

That's pretty much all I have to say in this thread until some ISP  
makes a move, in the meantime, it's more relevant to setup the  
tunneled networks on an individual/organizational scale...
