This 'driven by the desire of the application' is an illusion.
Any app that produces or consumes a continuous audio stream
is sooner or later driven by the sound hardware in some way,
no matter how you twist or turn it to hide that fact. There's
no escape from that, unless you have infinite buffers or
adaptive resampling. It doesn't even matter if you use
callbacks, blocking read/write, or whatever.

The only thing that varies is the amount of buffering.
It shouldn't be so difficult to create a lib that solves
that problem for non-realtime apps using JACK once and
for all.

The real problem of 'deskop apps' w.r.t. JACK is IMHO more
the fact that JACK doesn't provide access to some parts of
some soundcards, e.g. multimedia codecs and the like.
