I haven't yet had a view in detail, but I guess if JACK would 
be the common layer. MAS could reside on top of it.

The questions are:

* Would JACK be stable enough? I guess yes. Furthermore, we 
can make a deamon which restarts jack if it dies

* Is JACK secure enough? Certainly jack would never be started 
by any distribution per default with realtime privileges. But 
this is not needed for the common user, so users who need it 
can turn it on later.

* Could JACK be started during boot time and collect audio 
from any user? As discussed before, this is not necessaryly 
needed, JACK could also be started as soon a user logs in. 
But I like the idea that I can have multiple X sessions and 
every of these users can play audio

* One problem remains, JACK cannot use different soundcards 
because of the cards quartzes. So, would we have to start a 
seperate JACK instance for each card?


 Thanks for your thoughts & best regards
