Band Hero DS includes a 'drum skin'

Activision just announced the launch of the Band Herosite, with a contest whose prizes include both a console Band Hero bundle and a DS Band Hero bundle. The official rules for the contest reveal a bit more about the DS offering (which isn't hard, since we've previously known nothing at all about it).

Predictably, the Band Hero DS Lite Band Kit includes the Guitar Grip peripheral included in previous Guitar Hero On Tour games. However, it also includes a "drum skin" peripheral. We ... can't imagine how that would work on the DS (does it sit on top of the touch screen?) so we've emailed Activision for more details. Band Hero wouldn't be the first DS game to simulate drumming, but we don't know how it would work with a peripheral.
