Each process connected to the bus has a "unique name", and the bus
will send you notifications (NameOwnerChanged) when those names appear
or disappear.  A pattern used by some programs like bluetooth is the
"agent" pattern where the client sends a "Register" message with its
unique name, then the server monitors that client and sends messages
directly to it.
