Yes that sound reasonable. It's probably also worth to think about a mechanism
to explicitly set pcache to "offline" mode. That way on a client machine a
hook could be provided for e.g. NetworkManager to bring pcache to offline mode
immediately when the network goes offline.
That mechanism could either be offered through back-config (back-monitor as
for readonly?) and/or through the nssov Socket as that would most probably be
the main user of this disconnected pcache mode.
