I could be wrong, but I don't know of any PDA that will run a program which
is loaded on the hard disk of another computer. Most PDA nav. systems are
loaded on the solid-state drive of the PDA and are cut-down versions of full
programs.

The I/O device for the laptop which you mention would surely be a Bluetooth
GPS.

Using a wireless multiplexer, it may be possible to install such a set-up,
but I have doubts about a PDA being able to run a program that was not
designed for Windows CE.

You could have Bluetooth on all 3 items of course.

Such a set-up would send the necessary data from the GPS to both the laptop
and the PDA. Is this what you want? You would have to check whether NMEA
protocol can split the sentences and send them to 2 devices.
