Ok, so tell the rest of us what this means.  I have a very fuzzy,
grey, fog-like definition in my mind of what you're talking about.

As I understand it, multicast allows you to broadcast 1-to-many, but
I don't know whether individual clients have to "register" somewhere
to be able to receive these broadcasts.  I would expect so, as
broadcasting these things everywhere on the 'net at once would clog
up the 'net awfully fast (with lots of broadcasters at once).

So what's the procedure for a client?
