I do that in ubuntu jaunty:

there's a mechanism in ALSA that lets you use jack as output for ALSA
only applications:

http://alsa.opensrc.org/index.php/Jack_(plugin)

I have this on my ~/.asoundrc

pcm.!default {
type plug
slave { pcm "jack" }
}

pcm.jack {
type jack
playback_ports {
0 system:playback_1
1 system:playback_2
}
capture_ports {
0 system:capture_1
1 system:capture_2

This means that the ALSA "default" device should be redirected through
the "jack" device.

For this to work I had to recompile the package libasound2-plugins,
which did'nt include the alsa jack plugin in stock ubuntu.

And it also means that when you're not running Jack, ALSA applications
will complain (but you can always move the .asoundrc somewere else to
restore the original functionality)

I'm able to use almost all sounding applications through jack this
way, including skype and the flash plugin for firefox (from version 10
up). Those are not realtime safe, so they make some xruns... But I
turn on jack in the morning and use it all day long and all is working
quite well.
