[AG-TECH] Multicast Issues

[John I Quebedeaux Jr]

Ran events via NCSA yesterday (a couple) and just did a test to VRVS as 
well via the NCSA venues for a site we're meeting with tomorrow that 
doesn' t have an AG (sigh). Seems okay there.

When you check, be sure you are receiving AND sending multicast. It's a 
real kicker when you think all is fine because you can receive the 
lobby videos but in reality you're not sending anything. The beacon is 
very very useful to determine that.
