I think SIP+RTP over QUIC might be a contender for that title. No more NAT traversal wackiness caused by needing both a TCP connection and a UDP connection. I still can't figure out why SIP didn't use TCP-over-UDP for the low-bandwidth control packets.

QUIC has protocol-level support for running both a reliable (TCP-like) and datagram (UDP-like) substream over the same QUIC connection. Cannot wait for SIP-over-QUIC!

When SIP first came out, UDP wasn’t safe through NAT like it is now. Lots of cheap home routers would just wreck it. It’s gotten better since then.
