Personally I'd go with something like X10 too, but what about modifying a Clapper? ("Clap on! Clap off! ") And speaking of Clappers, I vaguely recall there was a device that used a 'squeeky' ==> remote and transmitter deal.
As far as 'low tech', maybe plug a relay into the switched outlet along with the light (cube tap to split -- I use them with the X-10 receivers here). Low voltage wiring along the baseboard and around the doorframe to a relay by the other lamp. First relay has a 120vAC coil; second a low voltage coil to match the control signal. ..Actually you don't need the first relay: plug the wall-wart/trans- former directly into the switched outlet (via the cube tap). This would provide a control signal directly.
.. Y'know, with the proper X-10-type stuff you could could also dim the incandescent lights.
