it's radio. encryption won't help with DoS. There is no such thing
as admission control. Anyone can broadcast garbage on the band

I've seen some AP's that seem like they don't have the CPU power or
NAT table size to handle normal bittorrent, so I don't doubt that you
might have seen a problem with too many associations. but the answer
is to get an AP that's not a piece of shit and doesn't crash. auth
isn't needed for that.

you just set up plain ipsec behind the AP. you can use cisco ipsec
which works well, but costs a fair bit on ebay to get at 11g/11a
speeds. It's complicated to configure but works well. or else try to
use ipsec-tools racoon or openbsd isakmpd or whatever. all probably
support XAuth, which is what you need to use ipsec with RADIUS. You
also need the mode-config extension which they all support. And you
don't need nat-traversal, which AIUI is still a stupid patch on
FreeBSD, and on all the BSD's it fails to do PMTU-D the way Cisco's

It's not unusual for companies to run EAP and the wpa-ish L2 auth,
802-dot-somethingorother, even on wired jacks. logging into a jack
with a username and password, or with an X.509 cert, is supported by
both Mac and ExPee.
