I have compiled integer versions of libmpcdec and the console Musepack audio player mpc123.
I searched all over for an integer version of libmpcdec but all the packages I tried were too slow, so I suspect they were compiled as floating point. This version is fast enough to web surf etc while playing back Musepack encoded audio.
I think mplayer could be compiled against this for fast Musepack playback. Would be nice to be able to play Musepack audio in Quasar.
My Z now has access to my Musepack encoded CD collection, which has made me very happy Hopefully it will be useful to others and hasn't already been done.
