If you use a USB plug in GPS on a Mac running both OSX and, say, Windows in Parallels, does the GPS service both, or do you have to, somehow, route the info?

And how many USB ports might be needed at a nav station with SSB email, printer (for the WXFax), GPS, etc.? Or do you simply use one at a time? I can only assume that two OSs would affect this number.

If any of your nav apps that are using the USB GPS are capable of providing a TCP/IP server, you can share it between the 2 "machines" via TCP/IP.

I would think the easiest solution to this would be a USB Hub. Keyspan makes a 4 banger, I believe.

Interesting question weather TWO Operating Systems on the same hardware can both bind to a single usb port.

If you used a hub, I wonder if it would act as a repeater and then you could pug the same data into two usb ports on the computer and each time you would be asked which OS to bind to? Probably won't work that way. USB is bi-directional and likely assumes a conversation between only two objects. Worth a try.
