Well I guess that may work to some degree, but would get me fired here as it would remove America Online as well, or at least severly cripple it.

We allow our VPs and Traveler to use America Online as it has proved beneficial for ease of connection when in Foreign Countries.

Removing ONLY AIM would be a better approach in my opinion, but hey... if that is what or how your Company wants to do it, that is fine as well.
