Thanks everyone for the responses.

So far the Anders' suggestion of using screen.nas seems to have the most promise.  Torsten: I have another project I want to use the fgpanel system for, but with this project we are trying to keep the logistics of starting things up as simple as possible, also I'm not sure how you would keep the fgpanel display in front of the FlightGear display if you had to click on the flightgear display to interact with it?  Hal: it's important with this particular project to have the instrumentation attached to the screen when the view changes or pans around, even in tower or fly-by views we want to see the instrumentation clearly.

Regards,

Curt.

Have you thought about modeling the skydiver as an "aircraft" with the "cockpit" being the view out of his/her goggles? The "panel" would be nothing and the instruments could be just positioned about a meter in front of the pilots point of view. You could then keep the instruments in view as the "pilot" changed his view direction (IE. look up, down, left, right) by rotating them about the pilots head. You should be able to do all of this using the existing XML. Or you could create a 3D model for the skydivers body and possition the instruments on his/her body (IE on the top of the belly mounted chute pack) so that you need to look down to see them.
