Philips compact fluorescent bulbs with built-in photocell automatically turn on your porch lights

I recently reviewed the Belkin WeMo Switch and said it was one of the steps I was taking to automate my home and increase its security.  The Switches work great to control lamps plugged into outlets inside my house, but my porch lights don't plug in to an outlet.  I had first thought that I might use the new WeMo light switches with my porch lights, but I think my house wiring is too old to use with them.  I like to have my lights automatically turn on and off with the sun, and I used to use a screw-in base with a photocell when I had different fixtures and used incandescent bulbs.
