although in theory i agree with you fons, i note that firefox and a
few others from the mozilla stable have realized that with
"heavyweight" X apps, this is not *always* true.

i certainly think that for an app of qjackctl's size/nature, checking
to see if its already running *on the JACK host* can make sense, but i
don't see how it makes sense to ask the same question about a display
server. what is the scope of the resources that qjc has implicit
control over? the audio interface and/or jack server on a given host.
what is the scope of the resources that the X server has implicit
control over? itself and the screen it controls. given that these are
not linked, and qjc is a lightweight application, running N or more on
the same X server seems to me to be something that should "just work".
