Nice, here is the current progress of my Silvia / PID monitoring: http://i.imgur.com/mis4L.png.
I'm using Arduino + TC4 shield for PID and interfacing w/ thermocouples, SSR, and opto-isolators (for front panel switch sensing). Serial to RasPi to web sockets for the frontend.

I use this with an iPad standing next to the machine to check that the temperature is okay before pulling a shot. The temperature controller is implemented with an Arduino board.
