FWIW, I spent the better part of today reviewing our UDP plans[1,2] and pondering this design, but I think I've decided this is not terribly useful to us right now, primarily because it would seem to require the very same circuit crypto changes as we'd need for a full client-to-exit datagram transport (to support reordering at the circuit crypto level). 1. https://research.torproject.org/techreports/datagram-comparison-2011-11-07.pdf 2. https://research.torproject.org/techreports/datagram-testing-plan-2012-03-16.pdf -- Mike Perry
