So far it seems that there are no ready-made 9P-based solutions available for what you have in mind. At least I don't know of any. In any solution available there are costs to pay (economical or temporary ones). So I could write the code missinig, if the time required to write the

Have you done a literature search? I don't get the feeling that you have. You are right, I searched over the net only about Plan 9 filesystem replication and so... But I was always searching for a plan 9 based solution. I already have some alternative solution (linux based), but I would
