Basically some universities have this god awful program called Cisco Clean Access Agent. It forces users to login to a 3rd party client which checks to make sure users are 1) registered to the university servers and 2) checks to make sure users have an up-to-date antivirus. This makes using Xbox 360's Live difficult because one cannot verify that they are a Student. According o some forums, Cisco has the Xbox MAC address already blocked since all Xboxes have similar ID's.
But now there is hope, here is one of a couple ways I got through my universities firewall, muahaha.
First off, log into clean access agent as you would normally.
Step 1Open Command Prompt

Now, after logging into the network and having access to the internet, open of the command prompt. Easiest way is to Click Start --> Run --> in the text box type CMD then click OK.
At the command prompt, type: ipconfig /all
This will list all your network identities and settings, hurray.
This picture below only shows a fraction of the networks, don't worry.
The possible upside to this is the the network may not every ask you to "re-authenticate" your computer since the router will always be on and connected.
Another upside is that you can have the xbox and computer connected at the same time, both will always look like one computer is connected. As well, if the authentication does time out, you simply re-authenticate with your laptop and continue on as normal. No more unpluging things.
Good luck, but certainly worth a shot and much simpler. :)
To answer your actual question: All the CCAA does is tell the server that the computer who uses this MAC address is clean and allowed to use the network so dual-booting Windows to run it will validate your machine and you can run OSX with network access. Depending on the server's retention period you may only have to boot Windows once a week or less.
