H Jamey, finger bounces are pretty common in quibeqcois and irish playing, usually they use more than one finger, like alternating triplets with your index & middle finger. Or a roll with three fingers on one button, mostly in ring-middle-index finger sequence.
One of our posters (i guess) uses as it seems a single finger bounce on Midland two step, see link #3: http://nl.youtube.com/watch?v=k-1AGzkjTcI
PS he has a slow version posted too, but omits the tricks there - nout
