Can multiple users access apps purchased from another Apple ID account?

I have several iMacs under my control. I need to find a way to download iLife using one Apple ID, so I can have all users on each machine to also have access to the updated iLife suite.

Is it possible for other users to access an app that was purchased from another Apple ID. If one purchases an app, does the machine allow access to all the users?

(I know those two last sentences are redundant, but I want to make sure everyone understands problem).

I've read countless articles on this, and can't seem to catch a break from the problem.
