the need for a UDP scavenger service is strong.
Speaking for myself, I would suggest (a) getting your favorite ISPs to run a scavenger service (IP layer), and run DCCP over it (transport layer). DCCP has similarities to TCP in that it has a duplex connection and manages throughput; it differs from TCP in that it does no retransmission. The purpose of the window is to control the rate - like TCP, DCCP sends one window per RTT, but unlike TCP it discards any excess that the application might give it.
Running UDP over a scavenger service, you fill a lot of pipes with traffic that will presumably be dropped later. Running DCCP, you drop that traffic in the first place.
