Very cool!  I could certainly take two of these.  I have been looking for some 
USB GPS receivers but I have absolutely no idea bout them.  It's tough to find 
one that seems reasonable/reliable.

Makes sense.  I'm looking at buying ~20 GPS chips and soldering up my own boards 
for them.  This way if the chip fails all I have to do is replace that the rest 
of the parts will be robust.  They're going to be cycled a lot so I expect a lot 
of failures over time.
