In addition to multicast, today we should consider other inexpensive streaming
solutions available even with IPv6 support. They allow to broadcast the event
with lower bandwidths for those that can't get multicast, or don't have the
bandwidth to support high bit rates.

I contacted my ISP last week about getting multicast routing configured
and they spent days trying to get it working. They finally called their
equipment vendor, who explained to them that they need someone to route
to them, as well, which was news to them. I'm now getting an mbone feed
through work (I'm a telecommuter so it wasn't automatic).
You can sometimes get a multicast tunnel terminated by a friendly
department, if you've got such thing, but they're not as happy about
you pump a lot of traffic through them as they used to be.
BTW, the only multicast stream working during last night's plenary
was the MPEG-1 one, and because of the high bit rate it was very lossy.
The other, lower bitrate streams weren't working and the guy running
the service kind of blew me off (and I quote: "watch the video in a
couple weeks after we get back"). If the problem recurs during today's
sessions, please send email to them at
they'll see that I'm not a lone crank.
