I've got my latest networked temperature controller up and running, it's a Raspberry Pi board interfaced with a Teensy 3.0 32-bit ARM Cortex mini-board that allows you to monitor and control up to 36 1-Wire temperature sensors and switches in up to 12 different actions. It is capable of running on both wired and wireless intranets. The Teensy 3.0 is capable of using many of the Arduino libraries, and can be programmed with a modified Arduino IDE, making it a snap to use.
The Teensy 3.0 handles all of the sensing and control, and the Raspberry Pi interrogates the Teensy 3.0 about every 500 milliseconds and updates a web interface to show you the current status. The Raspberry Pi uses a LAMP stack to handle the database and web processes, so you can add or change programs in whatever language suits you. I use PHP and Javascript, but you could also use PERL, Python, C, whatever floats your boat
Once the Teensy 3.0 is setup, it can run autonomously, with no interaction from the Raspberry Pi. It will resume its last settings in the event of a power failure, with no input from the Raspberry Pi. The Raspberry Pi is solely for setup and display purposes.
I've started a Blog that outlines the parts and steps required to make your very own TeensyPi, and am in the process of designing a board that will replace the current Adafruit Pi Plate.
I haven't gotten the pages done for the sensors and switches yet, but they should be forthcoming soon.
Hope this is of some interest.
