You could probably block the destination IP addresses, though. It's
currently about 12 IP addresses.

Any user who's determined enough to get access to AIM will find a way
to do so. For example, if you lock the TCP/IP control panel, they can
simply throw away the TCP/IP prefs and restart to unlock it. They
could then restore such items as IP address and subnet mask, while
setting the DNS server box to whatever they want.
Another way would be to sign up for a Jabber account, then use
Jabber's AIM Transport to access their AIM account.
