Yes, it is available. It comes pre-baked in a lot of the custom roms over at xda-developers. I think they also have cabs for it.

I had it running on my Tilt (both the cube and just the standard TouchFLO bit) and it worked well. I don't use the cube anymore because SPB mobile shell does the same thing and does it better (functionally speaking), but the scrolling features are still active on mine and work well.
