Automate Software updates w/o Admin password entry?

Hi Folks,

Just curious about something: I manage 40+ Apple computers at my job, and there are certain programs that I'd like to update on their own without the Admin Username and Password. We normally disallow our employees from having admin access, as we don't want a glut of nonessential programs bogging down their machine, as well as if there is a way to botch their system royally through admin level permissions, they'll find a way to do it.

But sometimes I do get rather busy, and rather than have to field 40+ phone calls, screensharings, or on-site calls when,say, iTunes needs to update, is there a program that I can use that stores the Admin Password, and when a program asks for an update, it can check a preset whitelist, and install the update if it is there? I know this can be somewhat dangerous for things like going from 10.6.3-10.6.4, as sometimes things can break between versions. But I'm more referring to being able to get M$ Office service packs when they constantly pop up and harass my co-workers with their "Critical Updates".

I've also heard that Remote Administration on "Remote Desktop 3" may have a feature that can solve this issue. Is this true?

Thanks for the help!
