We use WPA PEAP 802.1x with AD (MSCHAPv2) with Vista nicely (even WPA2
on some networks) so I am a bit confused by your statements.
Our DHCP based NAC worked pretty well on 802.1x but we are implementing
Impulse for the fall for additional functionality.

We are redoing our wireless from scratch here at the college and I'll 
share a few of the options that we've considered. Our wireless system 
encompasses our entire campus and we want to seperate the students from 
the faculty. The faculty for the most part use laptops owned by the 
college so we can make some assumptions based on our setup of what kind 
of security levels we can use. First off we have a Windows 2003 Active 
Directory setup on our campus, all the computer's times are synced to an

ntp server and we have a local CA.

Before this we had one SSID for both students and staff with 802.1x 
authentication using their active directory credentials. This worked 
great as long as we didn't want to get any Vista machines on the 
wireless or people that don't have an account (think conferences). The 
Vista issue was the biggest reason we're redoing our wireless. The 
problem (I'm guessing, we never actually figured it out) was something 
to do with the root certificates and our self-signed server certificate 
(even though we had "Validate server certificate" unchecked on the
clients).

What we are currently planning is to use 802.1x authentication on a 
faculty/staff SSID as we haven't moved to Vista for them officially and 
don't have plans too anytime soon. Students on the other hand we can't 
control what operating system they have and it's a sad fact of life for 
us that most of them will be coming back to campus with Vista. In light 
of this we are going to be using a WPA key for the students and a 
captive portal to identify them. We haven't decided how long the timeout

for the captive portal authentication will be. We considered WPA2 but we

also run into the compatibility problem again, but have decided that WPA

provides a reasonable amount of security.

Our student and staff/faculty SSID both route to different VLANs. We use

a packeteer to limit the bandwidth on the student portion of the network

and let the staff/faculty have unrestricted access to the pipe.

I hope I have given you some ideas and would love to hear some 
criticism/concerns about this setup. If there are gaping flaws that I 
have missed it sure would be good to know before rolling it out.
