That's exactly what I wanted, thank you. I really don't know why I 
haven't noticed that this feature already exists.

I do not have any strong opionion about this. Maybe this could be useful
for setting up a connection broker that keeps running all of the time 
and waits for new (pairs of) clients. And it would be more consistent 
with the normal (non-brokering) behavior.

To be honest I just copied the text from the sbd man page and didn't 
really think about the client reconnection feature. But I guess it could 
be used e.g. in pentests to install a reverse shell that is 
automatically re-opened by the remote client if the connection gets lost 
somehow.
