It occurred to me (during communications with Mathias) this morning that one
downside with the VRP is the seeming rotation about the nose of the aircraft
in the view. If either:
1) The offset from CG to VRP, or
2) The CG position itself (being effectively the actual physical rotational
center)

Yes. I mean no you aren't, but yes it is already being done. ;-)
For anyone interested in this subject take a look at the
-set.xml files for
the pa28-161 or the p51d. Both add target-offset parameters to
the views.
These are offsets from the VRP (e.g. Nose) to where the camera should be
