Not big enough I guess (and it=E2=80=99s partly done in wip-guile-ssh, the
missing bits being mostly in Guile-SSH itself.)

Too small, I think.

It just occurred to me that this may be possible to solve it simply with
=E2=80=98socat=E2=80=99.

On the machine that runs guix-daemon, run:

  socat TCP4-LISTEN:9999 UNIX:/var/guix/daemon-socket/socket

On the other one, run:

  socat UNIX-LISTEN:$PWD/foo TCP4:the-other-machine:9999 &
  export GUIX_DAEMON_SOCKET=3D$PWD/foo

Does it work for you?

Thanks,
Ludo=E2=80=99.
