[AG-TECH] Mapping IP addresses to Venues

[Jay Beavers]

An example would be the deployment of AG nodes for virtual classrooms throughout a major state university system.  This could add up to hundreds of venues in use simultaneously fairly easily.
 
Not a problem using non-routable multicast addresses, but if the schools wanted to use publically routable addresses between schools, it would at least be a big topic of discussion ;-)

	What scale of address requirements do you have?

	I'd say it's a year out anyway. I've not seen mention of IGMPv3 support for the various L2 IGMP-snooping switches yet, and that's a prerequisite for an ANL rollout anyway...
	
	I'd love to be proved wrong on this ...
