Ok, that sounds good. I know that if I can get a bridge between the board and the terminal, I can do anything in the OS (power, volume, eject, cut/copy/paste, app launching, etc.), and moreover I can launch applescripts, from which I can do anything with any application (create new email to my boss that says I quit, etc). So it's really an issue of getting commands into the terminal...
I just ordered a couple boards (one for me and one for a buddy who's going to work on this with me). I'll let y'all know what I find.
