I don't think it's as easy as build the hardware and make it speak the language. The iFixIt teardown of the Kinect shows some beefy hardware -- the most interesting piece to me being the 512MB DDR2 it has onboard. This says to me that they're doing considerable processing on the device side, rather than putting it all on the Xbox. If that's the case, it'd be a considerable effort to replicate it. Edit: 512Mbit, not 512MB. Meaning it's highly likely that it's a fairly dumb device.
