All things related to multicast

["John J. Brassil" <>]

So this brings up an interesting point to me.  It has been awhile, but I 
think the reason I chose that address in the first place was that I wanted 
something that I thought would get filtered out if it ever "escaped" into 
the wild.   Was that a good choice for that purpose (local traffic only) or 
should I not be using addresses in this range at all?

More specifically, what I am doing with this group is hooking TV cameras 
into the encoder for our commencement exercises and streaming the mpeg feed 
back to decoders for the campus CATV system and a streaming media encoder. 
So I get sweet, sweet point-to-multipoint *and* if Mr Cloudburst comes 
along and we have to hustle from the lawn to the gym, my techs don't have 
to worry about crossing uni subnet boundaries.

I can envision the day when we'll want to pipe the mpeg stream off-campus 
as well, but of course in that case we'll being using a "routable" group.

Thanks again to everyone for helping out with this, next Joint Techs I 
manage to escape to, first round is on me.
