moc, xmms2 and others are client/server players. A server daemon is loaded and 
then CLI or GUI players play off that. The presense of jackd may be tested 
when the daemon is loaded which is how moc does it.

The command I have above was taken from xringd, a daemon that senses the phone 
ringing and can "ring" on the speakers in response. My applet uses this code 
in a full telephony applet for a speakerphone modem. SO I need by player-
command to sense jackd at each ring, not just when the daemon is loaded, since 
I may or may not be using jack at any time.

If pulseaudio worked, then this should do it. However, jackd is probably 
sensed (or required by the suggested configuration) when pulse is started so 
it may be little better than moc or xmms2 and this is not a solution or my 
applet. KDE's backend utilitlies may also set them selves on startup and be 
unchangeable after that.
