I see my recommended course of action has been seconded. :)

The trouble with a Hub would be that it will set the connection to half-duplex.

If Craig is trying to be sneaky and sniff traffic on the wire, then changing the duplex may not be an option.

The Linksys WRT 54GL's offer Vlanning and port mirroring with the DD-WRT firmware flash, and are quite handly little boxes.

According to 

the DDWRT will run on anything from 4V to 18V DC, but at 5V I'd definitely turn off the wireless and any extra functionality so as to use the bare minimum amount of power.

I'll give it a try tomorrow with a chopped up USB cable and see if I can get lights :)

The closest thing I can recall to an unpowered hub that was the old thin
net and thick net coax stuff. T-pieces and Terminators and Vampire Taps!
Oh my!
