The Beeb's HD multicast feed is about 23Mbit/s to the host, and we received
it at quite decent (subjective) quality here on a JANET-connected university 
site.   The feed runs continuously (as far as any 'as-is' test stream does :)
and this morning is pretty flawless. 

The interesting aspect of the HD stream was seeing how various systems coped
with the CPU load.   It was good to have some HD content available that
encouraged people to install vlc, find out a little about multicast, and
system issues in receiving it.

Thanks again Beeb :)
