Some other reliable protocols built on UDP are 1) RUDP, made by Bell Labs for Plan9, which has a draft RFC from 1999 and 2) SCTP, notably used by WebRTC. I think I can rule out SCTP as a good fit because it has multistreaming (like QUIC) and multihoming which are both unnecessary for OCapN. RUDP seems much simpler but anything that was ever deployed seems to use something that forks from the draft spec, but perhaps it's a good starting point.

@dthompson  
A nitpick, SCTP doesn't run on top UDP, but IP directly. 

It is widely used on telco, but Internet middle boxes usually mess up with it. Something on top of UDP would be more reliable.
