Focus/Zoom Combo Effect

How do they do the following effect and how would/can I do it on a prosumer camcorder?:

The zoom/focus/movement camera trick at the 31 second mark of this video...

They are zooming out while trucking the camera forward. This decreases the focal length while keeping the subject in the same position. You can do it with any camera really, but it would probably be hard because you typically don't have good control over zoom with con/prosumer cameras.

saved me a lot of time of random experimenting!

It's called a Zolly or vertigo shot.
