Fair enough.

(I think it would be possible to arrange for batching when dealing with
streams too, but obviously we don't have that yet.)

I would prefer there to be no isinstance(..., RemoteRepository) checks if
possible.  I just removed those! :)

If you want InterDifferingSerializer to work, then make it not assume a
KnitRepository.  i.e. I think you want an InterRepo that isn't a subclass of
InterKnitRepo to do this conversion.  I'm not sure if that should be
InterDifferingSerializer or something new.
