There is no code yet to do that with borg2, but at least we do not have 
the crypto issue there (no aes-ctr, new session keys per backup, no 
counter to manage long term).

So guess one would only need to change the repo-id to have separate 
cache/config storage.

As it is now, "borg2 transfer" copies all archives to the target repo 
(by default).

If you copy the whole repo, you also get all archives, but you can't 
"mix" anything.
