I'm indeed not a native English speaker. And I apologies for not having diagrams, in fact I was working on this part right now... And planned HN exposure little later after more diagrams are added to website, VirtualBox image ready with whole environment to save time for folks who want to experiment and a well tested initial version separated from development branch.
However it went out earlier, uncontrollably, while I'm travelling... and I will play now a catch-game...
Well, sure, but there's no high level overview. Even something like "It's a virtualizing solution, like Xen/VMware/VirtualBox, that uses Chrome's Native Client".
the prose is poor - perhaps not written by a native English speaker - but its very technical, accurate and not BS
