It should be as simple as require ‘drb/udp’ with DRb-2.0.4 (builtin does
not have drb/udp.rb), and using drbudp:// URIs.

Unfortunately my simple example is having problems.

Warning: udp is not reliable. You may be aware of this, but for
something like drb, it can be a disaster if a reliable negotiation
protocol is not built into the way drb uses udp. Even on local
networks, udp packets can go bye-bye.

On the plus side, udp is really fast, fixed length- a real datagram
instead of a stream.

Missed your ssh tunnel hell. Done a lot of that, but with relative
success.
