numpy comes with some utilities for working with ctypes and numpy
arrays -- you certainly should be able to do that without a copy. Poke
around in the numyp source, docs, and mailing list.
If I understand the docs right, this makes it really simple:
note that there is a lot of great stuff going on with numpy and
Cython doing this sort of stuff -- numpy arrays may be a good bet anyway.
You might also want to check out geo-Dango -- I think they've got a
pretty complete wrapper for GDAL with ctypes
