[AG-TECH] Venue Server Installation

It's a very small node - 100MHz Pentium, 128M RAM, Jeremy can
fill you in on the disc space, which I think is sorta sparse.
We'll help in any capacity that we're able :)

But, he did just create a MooseDrool room and the two of
us need to figure out how to go about getting multicast
addresses associated with this, and neither of us have
a clue.  

Michael/Bill - you can expect to hear from me :) :)
Plus, Jeremy and I will go through some of the old list
archives that "seem" to address some of these issues?

If someone has a quick "cookbook" method on how to get
Class D addresses associated with this vv server, we'd
be appreciative.

Jeremy did a great job (I'm half way out of town now, 
Jeremy!! :) :))!!
