I think this is a useful distinction, but am wary of changing  
BaseStationCC2420 given that I'm sure many people use it with its  
current semantics. This would also require having a Sniffer and  
BaseStation for other radios, for example. The functionality you  
describe for BaseStationCC2420 above is provided by the basic  
BaseStation if you compile it for a CC2420 node.
