Hey Jonas et al.:
Thanks for the reply, forgive my disbelief on Clarification 1. :) If  
I'm completely with you, that is entirely unexpected on my part (and  
I've read this part of the spec a few times). Is this to imply that,  
no matter what the arguments to pushState(), if the path is relative  
to the current URL there will be no request for a new document and no  
user-agent initiated network activity?

This is a behavior I'm fine with and will meet my needs just as well,  
I was simply expecting to have to use the approach from Clarification  
2 in order to retain my document object. It does however lend itself  
to some confusion when paired with user agents that don't yet support  
the history portions of the spec as they will have to be handled with  
hash-based addressing while those that support pushState() will have  
more sane URLs--but that is no matter in the grand scheme of things.

Also, that would imply that the popstate only fires when you're  
navigating through history. Is that correct?
