For the lazy basterds (according to CanadianMaestro), the BDP-3 is operational via the Harmony Elite.
You can use the play, pause '>>' and '<<' buttons, other ones I didn't use so maybe they also work.
So if you're in a wheelchair or you can't move for another reasons like a broken leg (or according to CanadianMaestro you're a lazy basterd) this is a good feature and very handy.
