I have some fairly simple scripts (pulse-withjack and pulse-withoutjack)
which I use to load up jack when needed. Here's the general logic.

1. My default.pa uses module-udev-detect.
2. When I want Jack, I do the following (scripted)
   a. start jack
   b. load-module module-jack-sink/source
3. When I want to stop Jack, I do the following (scripted)
   a. find the module-jack-sink/source IDs
   b. unload-module them
   c. stop jack

This is of course with jack2 (with the previously-mentioned dbus-based
suspend of sound). If with jack1, you'd have to add logic to unload the
alsa modules before starting jack and reloading them after stopping
jack.
