thanks!

I'm personally strongly leaning towards having a protocol design that 
carries the namespace for *all* namespaces including user. Special 
casing the user namespace just for the sake of avoiding a clean design 
with a protocol version bump should be avoided.

As said before, I'm happy to help and work on the protocol spec and 
documentation side of things.

I suggest we wait for more feedback on the design from others, 
particularly Volker, metze, Jeremy and Tom.

Thanks!
