I've been using Things gateway for probably a year or so now (I'm just using z-wave devices, but Things supports lots of other types as well). The main thing I see missing that most home automators will want is support for locks/garage door openers/etc. The interior stuff like lights/alarms/plugs/sensors/etc. is all great. A lot of emphasis is on their Web of Things protocol that looks really cool and would be fun to play around with if you wanted to add your own home-made device (or hopefully more vendors will be adopting that protocol soon).
