with regards JANET and indeed the other places, its conceavable that you could setup the java mTunnel
http://www.cdt.luth.se/~peppar/progs/mTunnel/ as a server or 100+ on them, and use it in client mode at the NTL end user side to get these H.264 multicasts, any takers to set it up here and advertise the urls?.

if you want go a little better and include userspace dns and web server to make it easyer for a test of this,take a look at these rebol scripts
http://www.rebol.org/cgi-bin/cgiwrap...sync-example.r
and a whole load of simple fully working sample servers to plug the tunnel into for instance
