Transparent proxying is then the best solution in all probability, if you can
route all traffic through a mid to high end Cisco, or a linux box (I think BSD
will do it too...Not sure), you can (at the very least) run port 80 traffic
through your proxy server. Alternatively, you could block off port 80, and tell
people to use the automatic proxy config scripts in their browser. ftp will then
go throught your proxy as well, since they're unlikely to sit down and plug
addresses in manually if an automatic option is available.

It's annoying to have to do, but sometimes you have to apply some pressure to
improve performance for everyone.
