Obviously, it's hard to say that the time you've invested in making  
sure that only this more "open" protocol is supported hasn't bought you  
more than resource fork ugliness, mysterious long file transfer  
interruptions, filename handling peculiarities, and permission issues.   
Most of these things can probably be worked around, but that takes time  
that would've probably been better spent leaving things to AFP for an  
"OS X shop".

TCP/IP / ZeroConf / Rendezvous / LDAP takes the place of AppleTalk.

You're talking about AppleTalk again, I was talking about AFP.  It's  
well known that AppleTalk is indeed chatty, but I haven't heard anyone  
ever say that same of AFP.
