I got my raspberry pi to run pronterface to interface with my 3d printer.  There is an experimental branch that has a web interface on github.  I then followed this guide on thingiverse skipping the part about changing the python pronterface code because it is already enabled with the version I listed above.   I have to have a display hooked up to run the gui because it is required before you can access the web interface.  It does work though, screenshot later. I am now installing ffmpeg in hopes to be able to stream a webcam to watch my reprap print while I am controlling over my wifi.   High-res
