I think you're mistaking "interface" for "service". And in any case, multiple 
service names wouldn't affect the issue. You're actually looking for multiple 
*connections* and, probably, multithreading.

No, it has one message queue per connection.

No, you need more than one connection to go along. And you probably will need 
multithreading, which is a problem for dbus-glib.
