Hum, didn't think of that. That would be a neat idea. There are a few different versions of the RPI that were released and they all have slightly different GPIO pins available. To get p14p to work on it would be a bit of a challenge, but would still be a good idea.
My own time, like yours, is somewhat limited, but I would be willing to help when you get around to it yourself. I currently have two RPIs both are Version Bs, but one is a rev 1 and the other is a rev 2. They have, as I said, slightly different GPIO pins. I use the rev 1 to experiment with and the rev 2 as an XBMC server for my TV. Only the rev 2s are available now and they have 512 megs of memory instead of 256 megs. Price for both revs is the same however.
