I took a very quick look at UDT and I think it's quite interesting. The
basic approach has appeared before (people were discussing the
"long-fat-pipe" problem in TCP even before the WWW came along), but I like
the optimizations in this one.

If I read their material correctly, UDT is based completely on UDP so
there's no need for you to create another protocol at the IP level
(analogous to TCP, UDP, ICMP, etc). That means you don't need raw sockets,
which makes your task considerably easier. You don't need to construct the
IP header either.

Instead, implementing UDT is analogous to rebuilding TCP inside of sets of
related UDP packets. Is there any particular reason you want to do this in
Ruby rather than just wrapping a C or Java implementation?
