Virtual Venue Information

	see: http://agschedule.ncsa.uiuc.edu/venues.asp

Key to editors:

	??	Anyone care to fill in this section?

	***	Doesn't this actually apply to machines on which a beacon is started up,
		not all AG node machines?

	!!!!	I suspect some of these 'clients' should be servers.
