That's the big issue that comes to my mind.
That can be solved. (E.g., provide a synchronization mark and encode application data to escape the sync mark and the escape mark.) The flow/congestion control issue is really the big issue. I guess one might like an unreliable but flow-controlled datagram stream transport. If one wants that, right now one has to build that atop UDP. The idea being that packet drops do not require retransmission, but ACKs are required to provide some measure of flow control.
