I think this is really cool and have been wanting to see something like
it for some time. Having low latency application response in regular
user space without hanging the system is the one key thing I think that
has been missing with Linux audio. Allowing settable CPU usage limits
also might allow for apps that don't have built in support for
SCHED_FIFO to be run this way via external utilities. Hopefully what you
have created will get the ball rolling :) Cheers.
