Here’s another idea: allowing ‘guix copy’ to talk to a “raw” remote
store—i.e., just /gnu/store + /var/guix/db accessed over SSH.

Just like we have (guix store ssh), we could implement raw store
operations over SSH using ‘remote-eval’ and (guix store database).  Hmm
that amounts to implementing a subset of the daemon.
