Hi Brian,
If you have general MIDI files of the songs you want to learn, I would recommend getting a software program called "Home Concert Xtreme" from Timewarp Technologies.
It won't wiggle the keys, but in its Learn Mode, it will highlight the keys that you're supposed to play and the accompaniment tracks will wait for you to play the correct key.
I made a video a few years ago demonstrating it on a Yamaha Clavinova CVP Digital Piano, but it works just fine on a Disklavier Mark IV:

Let me know if you have any questions.
