I have an old idea regarding webservers: peer-to-peer file transfer. The server would not store the file on disk, only the last transferred block in memory. Rate control would be done at TCP level: while the block is not transferred by the receiver, the server would not read again from the sender. I have written several HTTP servers myself, and I know it's doable, but the world does not need another webserver that only has this distinguishing feature. My question is if all of this can be done with Mongrel2?
