This is fantastic timing!
I just received my OSPi in the mail at the end of last week and am looking forward to starting some development work(playing) with it. I also just started working with node.js in a R&D project at work, and am excited about working with node. I am not sure if I have the node knowledge to be much of a contributor yet, but I will be following this project very closely. I already have node installed on the RPi, ready for the fun.
