robert: >As soon as you hack it, the UL/CSA rating is voided. a slight twist: how about one of those units that offer remote control of a mains socket with an IR transmitter? you should be able to hack the transmitter without loosing the approvals of the switching unit... not great but better than a kick in the teeth.
