Seems to me a line discipline would be the way to do this.  As I
understand it, the serial output format of most GPS receivers is pretty

updates and a user process can simply open and read /dev/gps0 (gpsN) to
get the current position.  A smarter driver could maybe even optionally
implement some of the techniques for crunching the numbers to provide
more accurate information. 

Now, even better would be a way to write to /dev/gps0 to _set_ your
