On the Mac, you can use the QuickDraw procedures Qd.GetPicture and
Qd.DrawPicture. Take a look at PICTbrowse in the MacPython Demo directory.

There are a bunch of varieties of IPC available. If it's on the Mac,
using AppleEvents may be the best choice. I have sometimes had
problems using IP socket communication on Mac OS9 and earlier
when both processes are on the same machine. ( OSX with it's unix
kernel doesn't show the same problems, although I think they can
be reproduced if both programs are running in the "classic" box.)

OpenGL would probably do it, but although the libraries are included
on the Mac, I don't believe the GL module has been ported to Mac, and
there may be some X dependencies in the SGI/unix GL module.
