At the time that the scripts were created, the OSC CLAM receivers (and 
the used liblo library) doesn't allow multicast servers (i.e.: allow to 
exist several OSC receiver servers in different threads in the same 
port) ... That means that if we want to use several sound sources, they 
should be in the same CLAM network, that could be very big... So: as we 
want to deal different sources in different networks, we used different 
ports for the sources.... And as you need the listener 
position/orientation too, the listener sends that data to all the ports.

Now you can use the same port in different networks if you install the 
latest liblo library and enable the multicast option on the receivers... 
Or as I imagine you did, just use one big network.

No, the receivers just use the port that you define.

Sorry, not ATM. :-/

But feel free to ask again if you have more questions.

Best regards,

PS: I'm testing the new Blender 2.5, so I expect to actualize the 
scripts to be compatible with it / Python 3.1 soon.
