Has anyone else started to implement this feature?

It's certainly good enough for Windows, where we don't have any
bibisect repos, but it would still be great on GNU/Linux so that we'd
have up-to-date bibisect that can be applied to any regressions that
pop up during beta testing.

Hmm. The buildbots are spread out in different locations, right? It
seems like the simplest thing would be to push the zipped install up
to the remote (source) server with something fault-tolerant like
rsync, compare a sha1 to make sure it got transfered properly, then
unzip and commit the files to the bibisect repo for that buildbot.
That would eliminate the need for each buildbot to have a local copy
of the bibisect repo.
