Exactly.

The particular bus daemon that's running defines a scope. The two bus
daemons predefined are the per-machine daemon and the per-user-session
daemon (system.conf and session.conf specifically).

You could define a per-intranet or per-internet daemon, but you'd have
to specify how and where it gets launched, and how applications would
locate and connect to it. D-BUS is really not designed for this though,
so while it would work I'm not sure D-BUS will have the right properties
for this sort of usage.
