I've been trying to use the alsa-lib-jack-plugin recently ...
It seems to works fine for me with the example configuration from 
alsaplayer can play things find through -D jackplug
This is great for being able to leave jack running when not doing heavy 
multimedia work, just playing background music.

However, it doesn't seem to work with music player daemon (mpd), my 
preferred music player.
I get errors like this:
ALSA snd_pcm_hw_params error: Invalid argument
Dec 30 19:44 : problems opeing audio device while playing "By Your 
Side/By Your Side.ogg"

I'll have to investigate further and sort it out, but apart from that 
alsa-lib-jack-plugin is a great idea
