The unit is, however, a lot more than simply a home automation PC. In their own words, Pluto is:

the only all-in-one solution for your home that seamlessly combines media & entertainment, home automation, security, telecom and computing. You can control your whole house with a mobile phone, a touch-screen tablet or a web-interface. A Pluto system is like an appliance - not a computer. It is self-configuring, maintaining and updating. No technical skills are required to use or install Pluto.

There are some interesting features on the Pluto, such as television programs following you (or your bluetooth enabled cellphone, more specifically) as you walk from room to room, the ability to instantly turn any television into a videoconferencing unit, using your bluetooth cellphone as a remote control, and the system sending live video to your cellphone upon intrusion detection, as well as turning all the speakers on in the house to give you the chance to scare the potential burglar off, or perhaps make a dangerous new friend.

The software is free and open source and installs on any PC. The company recommends that if you plan a large system with many concurrent processes (streaming video on one TV with a video conference on another, for example), you'll want more in the hardware department, naturally. As far as peripherals go, the company is supposed to list it's recommendations here, but unfortunately, doesn't seem to list anything yet.]]> http://www.househacker.com/permanent/Home-Automation-via-Cellphone-by-Plutohome
