[AG-TECH] Two Multicast addresses for video in Argonne Lobby

[John I. Quebedeaux, Jr]

Joe,

I'd hazard those two nodes are running different versions of the AG client?
My 3.1 clients connect to the 224.2.174.94 group and my 3.0.x clients
connect to 224.2.224.15.

I did let Tom know about this yesterday. I believe it's happened once
before.
