Well, I'd like to have some really automatic mode, which does
everything ondemand.

Once we've got this not just for repair, but also to support
quick partial clones that fetch more objects when required.

In fact, finally, I'd like to have some storage cloud where
data automatically gets replicated to nodes which need the data,
not just for VCS, but other purposes (backup, filestore, etc) too.
But before inventing someting completely new (reinventing much
of the wheel), I'd like to investigate whether git can be
extended into this direction step by step.
