 Just checked libarts C api - it's too simplistic (it's stream oriented, e.g.
there is no way to save a sample on server and then play it instantly when
it's needed).
 So it seems the only way that didn't require to extend arts C api (and
probably arts model and C++ API too) was to modify esd and hijack
audio streams that were going to hardware.
