Idea about the history horizon

[Nicholas Allen]

Hi,

I just had an idea about the history horizon feature. It might not be a
very good/possible one but thought I would air it anyway ;-)

I was wondering if it would be possible to have a mode where old
revisions could be retrieved in the background while you work (and
commit new revisions). So the horizon is always moving back (perhaps to
a maximum point in time or maybe eventually to the very first revision).

The advantage is that it lets you start working on the branch
immediately if you don't care about all the history at that time.
Eventually you get a complete mirror but you don't have to wait for a
complete mirror in order to start being productive. Bzr is silently
retrieving revisions in the background.

What do you think?

Nick
