[AG-TECH] AccessGrid 3: What information is available

	While we're on the subject of globus and stuff like that, will we still 
have to wait days in order to get a node up and running because of 
getting the certificates? It's one of the most tiresome things about 
setting up a new node.
	Also, something I'd REALLY like to see is the ability to set a 
site-wide configuration under Linux and Windows. Sure have the users 
have a .AccessGrid folder (or the equivalent under 'Documents and 
Settings' for Windows) but having a system-wide config would be VERY 
advantagous to me in setting up conference room AG nodes. Then, a user 
known to the network can log in and it's already set up with the same 
config everyone else uses. I don't like having to have just one user run 
the AG stuff, especially with shared apps and the possibility that new 
users want to get on the AG for a meeting, share their stuff in a 
conference and get off. It would be nice if they could use a site 
conference room and fairly much do it themselves, albeit with a modicum 
of training.
