Alternative to UDP

This feels like a bad idea to me - switching to a dedicated protocol would
remove a small amount of overhead, but comes with a lot of downsides, which
in my opinion outweighs the minor benefit of removing some of the overhead.

I have a strong preference for the continued use of UDP, because a large
amount of consumer networking gear can't handle destination NAT for
anything that isn't UDP or TCP. And even wth gear that can, using a
separate IP protocol would limit clients relying on destination NAT to one
client machine per public IP.
