I think it would be really cool if a p2p protocol could be added to fp.
It would allow people with slower connections to host their own files.
By utilizing the upload of the people watching, the downloads would be faster and more people can watch the same file easier.
This might be out of the league for FP programmers but its something i think should be considered down the road.
