BTW: a first version of the driver is available here:
  git://git.alsa-project.org/alsa-kprivate.git fireworks
  (this branch will be rebased)
At the moment, it has one fixed sample rate, no mixer controls, and
capture only (but playback already works in my even stupider userspace
test program).

Hotplugging and device aggregation should work just fine, although not
both together, i.e., ALSA doesn't allow changing the stream format while
the stream is running.  Is this possible with FFADO+Jack?

While potential users might disagree, I think more choice is better.
