Using a local only program on a mobile account in leopard.

I have a purchased and legal copy of a program that has a drm which makes it only usable in a local account on the computer but the user uses a managed mobile account. The software creator has said that they do not intend to make it usable on networked accounts. It requires having the cd in the computer to use the program which is fine but it just won’t work even though it has been installed locally on the admin account.
Anyone have any thoughts on getting this to work without having to log the user to the machine locally?
