This is just the use-case I want to solve with the NetECI + ecamonitor
Basicly, you start ecasound with 'ecasound -c --daemon', and then in a
separate terminal start 'ecamonitor' (comes with the latest 2.2.0-preX
releases). Ecamonitor is able to show current positions of audio objects,
effect parameter values, etc, all in real-time.
If you add an '-ev' or '-evp' (monitor peak volumes, suits better for
ecamonitor) to your ecasound setup, you can see see the current signal
levels using ecamonitor.

Yes, this is covered by edi-7. Unfortunately not much has happened in
recent times. What I'd really like to do is to clean up all ewf-code, see
edi-20 . This also means that improvements to current ewf code are on a
low-priority, at least for now.

I don't actually remember. :) I do remember that it stands for something,
but what... ugh, any good guesses? :)
