You could run Jack with the dummy backend and use zita-a2j and/or j2a
to add your HW interface.

and of course if you use jack1 (0.124.0 or later), these tools are built in to jackd, so that adding the device can be as simple as -A DEVNAME (or it can be a bit more complex if you need to specify different parameters from the server's own device, as you do).
