Of course, we don't know how long ago these Apple engineers worked for the company -- given that the App Store has vastly changed things over there in just the last year and a half, the tablet itself could have changed its focus in that same period of time. At this point, given all of the things you can do with a multitouch screen, finger gestures are probably the least impressive. But then again, Apple's been obsessed with multitouch for a while, so it's not a stretch to think they might be included some of this FingerWorks technology in a larger multitouch screen. Wait and see, wait and see.
Update: MacRumors now notes that some content on FingerWorks' website has been pulled despite being online since Apple made the purchase in 2005. Very interesting.
