I tried to explain this before the last time Linux Audio was slagged
off on this list as being a mess. JACK is for pro-audio users. Within
the IT industry, Pro-audio users are a minority, within Linux, they're
an even smaller minority.

C++ seems to be the language of choice for linux audio applications,
with a small minority using C.

I'm not trying to evangelize about how great Jack is, I just offered
to do a talk. If no one's interested I won't bother.
