Nope, I'm pretty sure he doesn't have one (yet), but I've accomplished the same thing with a windows box running remote desktop with a plm. It's even better when they go out of town and get someone to watch their house. There are webcams set up covering some of the main rooms, so I can watch the poor souls' reactions when I start turning things (lights, russound zones, alarms, etc.) on and off from 350 miles away. ;-)
If they can ever get FTT* in their area, I was going to see if I could link a MD to a Core over a VPN so I can access his movie collection from home. If that worked, then it would be even easier to f*ck with his (and others') minds, and I could do pretty much whatever I needed to with the Insteon interface.
Anyway, if you really want me to test an EZBridge also, I can probably convince him that he "needs" one (he gets dealer pricing anyway, so it's not that overpriced) - otherwise I can probably just figure out a way to simulate the same thing through an SSH pipe between the linux boxes in meantime. Just lemme know what you want me to do. Oh, and the download slowed down, so it'll be about 4 hours to completion now....(I'm getting anxious to try the new version)
