LinuxMCE is the only solution seamlessly combining:

media & entertainment with a server for music, movies and tv shows, plus a PVR and DVD Player,
a home automation system to control everything in the home with touch-screen tablet and Bluetooth mobile phone controllers,
a phone system with video conferencing,
a security system that feeds you live video on your mobile phone when something happens, and lets you speak to visitors through your stereos, and
a home PC solution.
A typical LinuxMCE system consists of a Core: one PC acting as a dedicated server and interface with all the sub-components. The Core includes our own plug-and-play back-end so it listens for and auto configures all sorts of devices like network audio players (such as Squeeze Box), IP phones and cameras. The Core automatically exposes a network boot for any other PC's or thin clients you want to use as Media Directors, which you hook up to your TV/Stereo's to use as set top boxes, complete with a media player, PVR, video conferencing, intercom, and a GUI to control everything in the home. All Media Directors work together seamlessly as a total whole-house solution.
