Hello, Joel,

Ok. My proposal is, that unless there's any alternative proposal, I'd
like this document to be pursued as "Informational" within opsec.

This is a nice quote, but... I'd like examples. e.g., start discussing
about which specific hardening proposal makes TCP more brittle.

That's not a problem.

Ok. Good. As I mentioned, unless somebody else comes up with an
alternative proposal, I'd like the document to target "Informational" at
opsec. I guess that at some point tcpm may want to work on some of the
stuff in the document on a piecemeal basis.
