Hey Buddy,
Good news is that I operate labs that run many non-networkable applications like Digidesign Pro Tools. The bad news is the current version of 7.1 does not support any use of non-admin users. There is a 7.1cs8 update available from digidesign that provides some sort of compatibility for non-admin users, but only local accounts on the workstation, not network users.
I talked to Digidesign support and they said that they are working on a new cs update that will provide compat. for network users, for labs like us.
However, Pro Tools version 6.9.2 works with network users when you chmod 777 directories that Pro Tools uses like Application Support, DAE Frameworks, Preferences, Digidesigns folder, and Pro Tools LE itself.
Hope this Helps!
Email me if you have any questions.
