New Bridge protocol

What about making all computers a bridge between computers, you know assigning a computer (its bandwith) between other two computers.

I'll explain myself. Computer A wants to access computer B. But it's very far from it, so TIME OUT.

Now, with this new method you could ask C computer, to download (like a bridge) files from computer B, and then download them.

So, some of your bandwith (when you are computer C) will be taken for others users to trade music, and your computer, will be a kind of server without being one.

See you in the future

If this is done, the bandwidth usage would grow exponentially, while not yeilding any advantages for 99.9% of users, and indeed making things harder on the server.
