Jed,

	First of all I am not an expert in MacOSX. But I have been working on a 
similar problem. I have written a wxWindow-VTK bridge:

	http://www.creatis.insa-lyon.fr/~malaterre/wxVTK/

	And recently, I decided to -blindly- add support for MacOSX. With the 
help of a wxWindow-Mac developper I tried hacking my code to support 
Mac. Download the archive, you'll find a file 
src/wxVTKRenderWindowInteractor.cxx

look for method: wxVTKRenderWindowInteractor::GetHandle()
it should help you.
Basically what I do is:
- create a window through wxWindow
- get the handle to that window (GetHandle() method)
- ask VTK to render in the particular window (instead of creating 
another one).
