However there is a distinct difference in a central numbering authority 
verses a central certificate authority.  The former has little impact on 
system security (presuming that everyone agrees / uses the same value 
for things) compared to the latter, which has significant impact on 

We can also operate without said central numbering authority if we all 
agree that specific things are specific values.  We can't (effectively) 
operate without central certificate authorities.  At least not given our 
current operating model at the scale that we operate ate.
