Sure. I'd be surprised if this is even possible. They only just
enabled keep-alives on their proxy/server a few months ago. (ie. every
request involved a bunch of TCP setup packets)

Personally, any sort of custom server, I'd probably avoid a UDP port,
and stick to just serving some HTTP. Once you open a connection, and
you can support pipelining, then many issues go away. (not the least
of which: dropped UDP packets)

Anyway... sounds like we agree Markus: they ought to start building a
server. It would help eclipse.org, and when deployed across the
broader community... big wins.
