I'm happy to see that Steve's proposal shares a fair bit of structure with the changes I have been making, in particular the breakdown into "determine the peer's capabilities" and then "figure out what to actually do given that information", which I think is key to helping readers understand things. Steve is being very aggressive about reducing verbosity; I'll need a closer read to see how much of that I agree with. One thing that I do see from a quick skim is the change to "Opportunistic Crypto-Security (OCS)" instead of the existing "Opportunistic Security". I don't think that Viktor (or the group) is likely to adopt that without the sense that we have a consensus for that term. Thanks for the rewrite, I look forward to reading it more carefully. (And thanks as well to Dave for the diff, it is handy.) -Ben
