Although we haven't engaged strongly with the HCE activities I'd like to 
put in a yes vote from Scapa.

I think the chief advantages that a binary protocol can't touch are:
        traffic logging and analysis by humans and generic components 
don't know particular command interfaces
        extensibility while maintaining backward version compatibility 
(old client, new agent) by using defaults for missing parameters

I think all other semantic issues could be satisfied equally by a binary 

vs. XML encoding. There are tradeoffs for optimization in various 
dimensions, but they're the same in underlying capabilities.
