Great write-up. Sorry to see the post didn't draw many readers. If I was benevolent dictator of the HN front page, I'd put you there.
I saw it got a bunch of upvotes on /r/netsec and came to hn to see if there were any interesting comments and was disappointed that it never made it here. Always a shame when the timing or whatever doesn't make it.
Oh, and too late to edit / delete now. Thanks for the write-up, super interesting!
