George,

I'm facing the same problem.  However, your question just caused a
lightbulb to appear over my head.

If you want to limit all your WinFrame users to a few sites, disable DNS
lookups on the server and force it to resolve names through the HOSTS file
(\WINFRAME\SYSTEM32\DRIVERS\ETC\HOSTS). The file would only contain
name->address mappings for the servers you wish to permit access to.
Patrons could still access other servers, but they'd need to know IP
addresses to get anywhere. (I'm sure somebody out there is saying "Well,
Duh!")

I've just tried this on NT workstation and it works as expected.   A proxy
server would be a better long term solution, but this could be a stop gap.
