A new internet controlled lighting project called SplashLight is being developed. It has 4 relays to turn lights on and off, and 3 PWM outputs to drive RGB LEDs. The core of the project is a Cortex M3 uC with an Ethernet PHY/MAC from Texas Instruments.
The project includes iPhone, Android, and web applications to control the board over the web. It looks like the PCB and schematic files will be made available in the future, but the license is still unannounced. Might be ripe for a remake.
