Well, that was actually one of the future goal of my 02' traineeship...
I got to have chromium use UDP for sending huge loss-insensitive data
such as the geometry, and correct ill effects (see
www.acl.lanl.gov/cviz02/Talks/12_Thibault/chromium.pdf and
ccviz02-chromium.ppt), but getting to a read multicast system (or broadcast
on a LAN) is much more difficult and involves rewriting much of
tilesortspu's flushing stuff. I already had to tinker with it to have
two streams.

But this is possible to my mind. I won't have time to do it in near
future, but why not later...

About your precise application, my udp/tcp/ip implementation won't be
helpful as such: I decided not to send lists via UDP, since I considered
they are sent once at initialization, and then only used. But one might
use a safe multicast algorithm to do it, I'll have a look (and this is
one of my school work at the moment, so... :) )
