For those using multiple computers and /or creating simpits some sort of interface software that could run an XML guage on a separate machine wopuld be a godsend.
That would allow you to do something like purchase the RealityXP "in-sim only" emulation of the Garmin GPS ... and run it on a stand alone machine as an external gauge.  Ditto other XML based stuff.
I think there would be a good market for this among simpit builders if anyone is game to give it a go.
best,
