AFAIK, the term was popularized by Rich Hickey in Clojure's implementation [1]. His talk introducing the concept goes into the etymology specifically. If I remember correctly it's something like "to carry across."

I'll agree that it's not possible without _any_ rebound, but you can easily simulate that kind of force. Where you would normally get a rebound from the drumhead, you use your palm for the rebound and fingers for the double hit. It requires more finger control, but as I mention above a truly proficient drummer has much more control over open rolls than just bouncing the stick and dealing with the rebound. Thomas Lang gives a good example of this.

It's not really a common thing to practice, and I only speak from my own experience as a drummer. But after a short while it's trivial to simulate an open roll fairly simply.

Anything high-performance is definitely out, though.

For most drum rolls, I find that good drummers will actually enunciate every hit. So you could simulate a drum roll with your stick in the air without too much effort. Buzz rolls and drag rolls (i.e. when your stick is literally just bouncing in high frequency on the drum head) seem to be impossible to simulate without a rebound force. I imagine, though, that the software would pick up on you doing any kind of roll and try to pick a sensible frequency and go with it.
