I tend to agree with you, and question if that is in fact true (it may
well be, my apologies in advance). DBUS is on my list of things to
probe, prod, and attatck due to data sharing.

But I'd be really surprised if data was available across distinct user
sessions. Unix/Linux are usually very good a separating processes and
sessions so that data does not comingle.
