The moving map aspect is tricky for the G1000 - including an Atlas- 
style renderer as another layer is possible, it'd also let me build  
the one GUI element I've been wanting for ages, a 'map' dialog box  
with navaids and airways overlaid, like the map UIs in MSFS / X- 
Plane / Fly. I'll definitely leave the moving map for the future, I'm  
afraid.

That's basically the approach that feels right to me, but I need to  
learn / be told more about the current OSG scene to be sure. I'm also  
unclear how the XML panel elements are handled in the brave new OSG  
world - are they mapped to custom nodes (which seems like it would  
work pretty well) or what (I'll go read the code I guess...)

The more examples of different appearances that exist for these  
things, the better - whatever the C++ solution is, it's going to need  
to be 'styled' with a set of textures and colours for each make of  
display.
