I also agree - subdividing would simplify re-use of common components -  
such as the discovery and security aspects.

 From the BBC's perspective: our original goals (enabling the creation of  
remote control devices that will work with many manufacturer's TVs/STBs)  
can still be met by profiling the use of a combination of these components.
