I just looked over the newly introduced
g_dbus_connection_register_subtree() and related data structures, and
I think it will fit very nicely with what I am going to need. All in
all it looks really sweet, good work.

One thing though is that as I read it objects in a subtree must be
known before method calls are accepted to them? For my use case in
Zeitgeist I was hoping that I could completely get rid of a "Manager"
type of interface, and just implicitly create objects in the tree
whenever calls where made to them. This does not look possible as it
stands?

Maybe allowing '*' as a wildcard node name in the subtree enumeration function?
