The lazy answer to both is "fail, or not, the same way as cups
currently fails, or not" (in fact, could the session printing service
simply be cups that treats the system instance as another remote
server?).

Ideally, I suppose, we would need a concept of "network identity", at
least for wireless networks (where NetworkManager already can
distinguish between networks) and perhaps even for wired networks
(where at least Windows 7 tries to distinguish between them, and in
some cases fails quite visibly).
