How about submitting a patch? Do we have to keep the python bindings themselfs or is it possible to have them generated upon 'make dist'? I would prefer not having to keep them in sync manually. Maybe this is related to your mention of 'semi automated bindings', but I don't get it due to lack of experience in python/C interfaces.
