I want all machines to have the same data, but if one of the machines
gets compromised I don't want the other machines replicating the
compromised data. I just want to keep all the revision history.
I don't care if a compromised machine sends compromised data if I keep
all the changes in the other machines I would be able to remove those
compromised changes.

A trojan/virus/spyware has access to the archive and can modify it.
I don't want the trojan removing version history and also that version
history being removed in other non compromised machines.
The problem here is that I want to keep all the revision history, even
if some machine removes part of it.
