Yes, we really should not have two drivers normally.  I think Konstantin
and Anton need to have a chat on how to go forard.  Without knowing the
details read-write support sounds like a killer feature we'd really want
if there aren't any code quality or other feature regression problems,
but I haven't had a chance to look at the code at all yet.
