Implement a form of transparent firewalling. E.g. all traffic towards
TCP/80 is redirected towards HTTP Proxy (this is the simplest form, you
can do it using a DPI product and sort out on a protocol basis i.e.
HTTP/HTTPS)

If arbitrary computers can open arbitrary connections to the outside
world, you have bigger problems :)

About the only way I can see you defeating employees misusing internet
is to limit their bandwidth. If I were a malicious user and worked at
your company not wanting to follow your policy, I would just vpn out
to my own server or tunnel my traffic over SSH so you couldn't see
what I was doing.
