Yes, that's dooable.
Edd Dumbill has been making a lot of changes and improvements to the
redland Python API after the 0.9.11 release - he can probably
comment. We were considering adding generators but that raises the
python minimum version as you say:

The API changes I don't mind, this stuff is still in flux.

That stuff may have changed in the latest snapshots.
Try it from
but I can't guarantee that it'll build at the moment, since I'm
adding new things and reworking some internals.
