NEED SOME SERIOUS HELP

I'm in a situation at college.  It seems our computer administrator has cancelled the access of AOL INSTANT MESSANGER and certain websites and MORPHEUS(a downloading program).  I was wondering is there anyway of g around this barrier.  I don't know what firewall we have but I do know he shutdown the use of other proxys.  I am in no way of trying to hack into the system, I just wondered if i cooud gain access to these programs.  His suppose reason is because it is such a big threat to the system, even though surrounding colleges are using it and having no problem.  They are trying to cut our rights since it's a private school.

I saw someone at my high school (which also blocks all im's) use port 80 (http) to connect with aim and it worked.

As for morepheus...you're on your own.
