I block port80 (amongst others) outgoing at a firewall level for all hosts
bar proxy server and my personal laptop (so i can prove things work or
not)

I don't have my DHCPD locked down, but the best thing I have seen for this
sort of thing kinda  comes out of

Basically defines two DHCP ranges based on MAC addresses, a known and
unknown.

Directs the unknown through a proxy that turns the images on the Internet
upside down!

These two combinations might give you some ideas and directions ;-)
