I don't think so, because I think the design decision to not compress
over repo boundaries is a good one. We can reopen the discussion if you
think the decision is wrong though.

This would require third party object access - like site to site ftp;
this is difficult to do with both security and peformance.

I think we should forbid the current behaviour. I'm not sure that
reconcile should fetch the parents, it may me that we have few enough
folk in this situation that we can just say 'remirror' or offer a small
repair script. (Because reconcile is heavyweight and slow, it may be
onerous for folk trying to stack to run it).
