  Hold on a second. Let me try walking through
this.

 We start qjackctl. Does it connect to a jack server at this point? If 
 so,

  always or only if jack is currently running.

 it connects only if jackd is currently running. 
That's what I thought.
...

  In cases where it might connect on startup, must
it? 
 no. again it only connects automatically iif a (default) server is found
 responsive to open qjackctl as one of its clients. 
Right, but does it *have* to do this? Is there no way to make this behavior a 
config option? Or a query on start option?

Config file is set to not attach on startup and so it doesn't. Config file is 
set to attach on startup and so it does. Or it sees a jack running when it 
starts and asks if you want to connect to it or not.
...

  Let's say no jack is running and we start
qjackctl.
 Let's say it doesn't connect to jack at this point. 
 i does not.

  Could there not be a setup option to indicate
what -n indicated now? 
 qjackctl -n command line option is just convenient for you to start jackd
 server with that precise server name and let qjackctl connect immediately
 to it as client to that same server.

  Let's say multiple jacks are running and we
start qjackctl.
 Is it possible to discover that multiple jacks are running? 
 nope. qjackctl will only "see" the default jack server or the one named by
 JACK_DEFAULT_SERVER environment variable at the time qjackctl is launched. 
Sure. it will only see it as things stand now, but is it impossible for it to 
see the others? If so, where does this impossibility arise?
...

  If so, would it be possible to allow a choice
from within the gui as to
 which one to connect to? 
 none atm. each qjackctl instance may only attach to one server at a time. 
I think we may be having language issues here. I am not asking here how things 
stand atm. Rather could qjackctl be modified to start, see multiple jacks 
running and list them and ask which you want to connect to and control?

Thanks for your time and responses.

 cheers 
all the best,
