has anyone thought about setting up a jack/ardour/pulseaudio howto
somewhere?  as i mentioned in another post  earlier in this thread, i
don think there is a potential userbase -- podcasters & audio editors --
for whom ardour would be a really excellent solution, if they could just
get it to work without lots of fiddling with sounddaemons.  is there
anyone who agrees with me?
