Currently kalsamix has an optional (config-time enabled) vumeter based on aRts.
In the end, googling for hours and trying to figure out how ALSA (undocumented) scope functions work (together with that fancy .asoundrc), I've found ameter (here), which is a nice app whose source help me to work the whole out.
This means that near in future I'll be able to add an ALSA-based vumeter to kalsamix!
