Multiplexing USB GPS Devices

We all know that the USGS has made its Topographic maps available for free download in the GeoPDF format.   Folks out in the field use these maps for a wide variety of different applications and a lot of the time, GPS tracking is involved.  The problem that we are seeing is that there are so many flavors of GPS hardware and protocols out there that supporting all of it is tough.  We came across a piece of software that helps bridge the gap between several different protocols and your integrated COM port.  Check out the Franson GPS Gate product for more information.  Could this application help ease the pain of integrating YOUR GPS device in to your workflow?
