Aaron, I'm not fluent on the 5510 per se; but if you are
authenticating to an external AAA server such as a RADIUS server you
might be able to set up downloadable ACLs and tie them to the users
who are to be denied Internet access.

The ACLs would permit traffic only to and from your internal network;
so if they tried to head into the wild they'd get denied - period.

Regards,
nick
