Ed Felton of freedom-to-tinker has released a tiny 15 line Python program called TinyP2P which allows you to create a simple (if not secure or scaleable) file sharing network. Get the code here. It’s cute, and might not be bad for tiny bits of file sharing.

Addendum: Actually trying to run it, I got
