I can understand your point of view. I also read Will Schroeder's opinion, and I
agree. I'm building a prototype application for 3D interaction of terrains, it's
not an open source project, but I'm using open source tools, like VTK. I choose
VTK because I like its design, but I'm still a beginner about programming with
it. For this reason,  I think a VTK's great value it's the support one can get
from the community. If you have some VTK code you think it's strategic for your
company you are obviously not  forced to make it public, but I thank you for the
code you added to VTK until now. If I'll be able to help you with the Flight
Interactor I'll be glad to do. When my (python!) code will be more stable, I'll
send you a copy  (maybe in C++, if you prefer...), even if I think your solution
is definitely more complete (well, mine has the picker :)).

Regards,
M.T.
