This is a bit "out there," but...

If there is no place for people to try their musical wings, make one. If you're at a college which has a largish room you can use, and possible a sound system, start a coffee-house. You need more people than yourself to get this done, I think. First things first. Put an add in the student (or hometown) newspaper to see if anyone's interested in playing. Put ads on bulletin boards. Start an acoustic jam session. Don't be surprised if only a couple of people show up at first, and don't give up - sometimes these things take a while to get started. While the session won't be performance-oriented, it's still exposure/practice, and will get folks together who might be interested in starting something more formal.
