A few things; firstly, have you seen the concrete proposal for a
repository level streaming interface I put up in april? It tried to
address all the cases then as well.

Secondly, I don't think the 'some revs are complete so we can commit'
will work unless you buffer all the revision objects and don't write
them as you get them, because otherwise you'll insert revs without all
their parents - introducing ghosts.

We can insert partial data for a revision anytime we want with no
trouble, as long as we don't insert the revision itself. But there is no
point in doing that, because a smart server will send that data again
anyway, unless you chatter down into the text keys and so on, and thats
rather pointless.

I think handling progress is useful, but can be done on a simple stream
anyway - for instance, just by including another attribute on each
record emitted.
