Belkin has what looks to be a nice basic home automation system called WeMo. Currently, the only app option is iOS (Android is in the works, though not out yet, in part due to the platform's fragmentation issues). However, you can also set rules up through the IFTTT website.
I figure, though, that a dedicated homebrewer or two out there could put together a webOS app that could get uploaded to Preware. If so, you've got an alpha-tester right here.
