The original idea was to be able to pair up DataChannel objects created 
with createDataChannel() on one side, with the corresponding channels on 
the other side (dispatched with the datachannel event). Since there was 
no guarantee that the dispatching on the b-side were to happen in the 
same order as the createDataChannel() calls on the a-side, the label was 
required.
