We use two networks.  Our AP's are "wide open" in that WEP, WPA, etc. 
are not used.  Once connecting to the wireless network, you are 
essentially in a sandbox.  The only traffic that is allowed off of this 
network is traffic to a Windows RAS server running VPN services.

We require registration of the MAC address (yes, we understand the 
imperfections of that).  Encryption is required on the VPN connection.

Right now, we have only one wireless network which is used by students, 
faculty, and staff.  A connected user has access to the same university 
resources as they would if they were at home (e.g. web servers, 
web-based mail, etc.).  Traffic outbound from the wireless network is 
limited to web traffic, SSH, and a few others.  There's a default deny 
on the outbound traffic.

We are, however, looking to deploy new APs which support multiple SSIDs. 
  Once this is in place, we'll provide varying degrees of access 
dependent upon which SSID you're connected to.  We want to have separate 
networks for faculty, staff, students, and guests, for example.
