Since I'm always looking for ways to be able to share files ... I recently ran across WiPeer. It is a simple little tool for sharing computers on a local network. The local network could be wired, wireless or really just some ad-hoc connection between you and that hot chick in class. Sweet right!? She's prolly like ... you are a big geek. Best of luck to you anyways.
Works pretty nice when you are sitting next to some nucklehead contractor that needs a file that you are working on and can't access the network because he hasn't got his login yet from the arse that hands those things out department. You know what I'm talking about if you are in the computer world. Ah ... it's the small things in life that make it soooo sweet.
Another handy tool from your good bud EdZachary.
