There is also new GPIO code somewhere, which supports features like interrupts. I haven't really seen it or tried to get that working (loos@ & rpaulo@ likely know more). I also don't know about RPi, I only have BBB which I can say works well and has lot of features, including some unsupported ones. Curses per some time period seems higher with RPi. Though, it's cheaper device... And you already have it.
