unless they specifically want any game that would exceed that limit to be banned (i.e. they might not really have video games in mind with their system but source just happens to go over the limit) then you can call your schools it dept and they might just tell you how to get around it, i had to do that to use irc when i was still in the dorms (was a port blocker in my case though)

i dont know anything about packet shapers but it sounds like you might be boned otherwise
