You might want to look at Cradlepoint - http://www.cradlepoint.com/. Never used
one on a bus be we use them in a few remote classrooms where we cannot setup
anything long term. Gives you the option to have more than 5 users and
multiple vendors by just swapping out the USB modem.

So I have this working right now but not real happy in how I got it to work.
Basically we are using policy NAT to give the server and the client the same
public IP address just when they go to Apple. Anything to 17.0.0.0/8 gets the
same public IP address. I'd like to refine that down but
Depending on your firewall hardware you may be able to get the details from the
WLC into the firewall logs. We use a Palo Alto and there is a document on how
to use the SNMP traps to associate a user at the firewall. See
