Alexis,

In theory this might be possible, but I am not sure what the state of
Python access to the warping algorithms is at.  Andrey, have you done any
work on this?

I'm afraid not.  My hope is that it operates similarly enough to the C/C++
API that looking over ogr.py and the C/C++ docs would be sufficient.
