Looks pretty cool. Can we make hydra do masquerading and have a 
hub using 10.0... out in the clubroom? Then people can come in and 
plug their machine in, with DHCP, etc. I don't know if hydra is the 
right box to do that - just raising the suggestion.

We should allocate some space in the clubroom for this, too. I often get 
people asking me to be around so they can install something off the mirror 
or ftp.uwa - it'd be nice if they could do this easily.

The diagram seems to imply buying another switch. This is probably a good 
idea to get 100Mb to the hosts in the clubroom that support it (when grabbing 
ISOs off the mirror, for example). However, should we do what Dunc suggested 
and borrow a switch and try it first?

Hoping not to have offended anyone this time :)
