Right.  And I wouldn't want to try to dissuade you from solving your own 
problem.  But I always keep one eye on the hordes who *do* want to bury 
aRts. :-)

I'm confused, though:  Jack likes alsa, artsd can use alsa, and the Jack 
page seems to say that alsa allows multiple accesses to the sound device 
at once.  Does that not work for you?

Hm.. you must have missed the months of whining Charles and I made. :-)

A serious point:  Stefan Westerfeld seems all too happy to answer questions 
about aRts.  Without his help I'd never have gotten anywhere in playobject 
and kaboodle development.  So I hope you ask if you have problems.

Heh.  I like fries, so that's good.
