Plazes - a location coordination machine. The rise of this class of machines hints at my second big thing for the Net this year: machines that extend the Net's reach in space and time from smart objects (those with chips) to dumb objects (sidewalks, barstools, busstops).
These are symbologies like Spotcode, Semacode, and their assorted readers. The real tectonic shift will begin to rumble when location coordination machines link up with Net extenders - thus massively slashing the transaction costs of accessing a web of 'dumb' objects whose intelligence has been unlocked. Think about the value prop for a second - I think it will be a biggie.
