Interesting stuff! Good to have you on board.

Comfort is one solution - the serial interface protocol is 
documented, and I've had success with interfacing it to Homeseer 
already.

Ian has a headstart on this one -- see the resource links he posted

I did this a couple of weeks ago - interfaced to the parallel port of 
a linux box. It's already xAP enabled, but I haven't got round to 
posting the circuit details (which are trivial). Works really well, 
although I needed to power the cameras off a single supply to avoid 
ground loop issues.

Excellent!
