Or you could give up on looking for a specific bus name, instead scan
all bus peers to find out which ones implement a specific interface.

Perhaps we need a pair of signals, “interface request” and “interface
reply”. One peer can ask “does anybody implement interface X?” then
listen for “I implement interface X” responses.
