I really don't have that great of a handle on what I just read, but does this product potentially offer the ability to set up an RTK base and a rover to pair with it for $800 each?  It looks like they are working on ways to communicate the correction from the base to the rover via 900mhz. radio and/or cell phone hot spot.  I'd be very interested to see how this works out once some people actually try to start incorporating it on their farms.
