Wah I guess I got the wrong end of the stick, I was really responding to
the "software shouldn't hold the thing up" aspect.

The vibrator does have some amount of PWM ("intensity levels") support,
how repeatable that is over different devices I don't know.  Also it
would be fairly do-able to put curves of vibrator intensity over time to
some extent.  But in the end what we have is an electric motor with a
funny shaped bit of metal on the end to work with.

It wasn't clear from the pic on that site what this "actuator" is, it
could be basically what we have.
