I checked it on Xubuntu: running Pulseaudio as an audio submixer through JACK . In Pulseaudio's mixer GUI (which is the default mixer in Xubuntu's panel), JACK can be selected as destination for an application's audio output, but only when the application is indeed delivering audio. For example, when a video is playing in Firefox, the audio interface option boxes appear.
The pulseaudio mixer allows you to set sink per application. This is under the "playback" tab, which only shows currently streaming applications. You can also select jack as the default output under the tab "output devices", in which case all applications will use jack by default. It's the button that when hovering over it says "Set as fallback".
What you need to install in order for this to work automatically: jackd2 (and start jackdbus, not jackd) pulseaudio-module-jack (the jackdbus_detect module)
It is possible to have PA create or destroy sink and source for jack manually as well, using the pactl tool. This will also work for jackd (jack2 only).
