Z depth tracking

Can Commotion track an odd shaped region of a scene that is zooming, and apply that data to another clip, AND allow you to scale and adjust the other clip to fit properly while maintianing tracking path?

That is a run on sentence! I have been doing a lot of tracking in After Effects and am sick of it's inability to track z movement unless is it a semetrical region (pinning)

Thanks,

Thanks Matt. Which version of Commotion supports this?
How little can I spend for motion tracking?

Thanks,

Ouch.
