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.
