V2M is no using JACK but direct ALSA access. This error is because CLAM can 
not access the soundcard because jack have it. It should be a nicer error, 
though. A regular exception which can be caught by the application or a 
status flag the application could ask after initialization. Any 
volunteer? ;-)

BTW, nice introduction. The server was ko but i found a copy here:

The backend concept you explain there seems somehow limited. Backend are not 
just jack or portaudio but also Ladspa, VST... which i think is the cool 
thing of having backends.
