I think my main concern is getting packages into a synth-recognized repository.

I would use NFS rather than http.  I would need to be sure to disable server in the conf, think I just did, now need to check on the other computer.

I don't really want to have to rebuild synth and dependencies redundantly after all are installed on first build-host computer.

But I would want to use synth on either computer without depending on the other computer; what I am concerned with now is getting started.
