Just ran across this looking for some wifi gear and thought of the home grown controller fans out here. 60$ at sparkfun and they seem to have rolled in the relays,temp sensor feeds ( add our own sensors ) and a basic command language over USB so no need to go after an arduino if you are looking to get something off the ground fast.
Certainly looks like an interesting starting point.
