+## TLS transition strategies ##
+
+While [RFC 5081](http://tools.ietf.org/html/rfc5081) is quite a while
+off from widespread adoption, it would be good to have an interim
+translation step. This is analogous to the SSH work we've done, where
+the on-the-wire protocol remains the same, but the keys themselves are
+looked up in the OpenPGP WoT.
+
+Firefox extensions that deal with certificate validation seem to be
+the easiest path toward demonstrating this technique. We should look
+at:
+
+* [SSL Blacklist](http://codefromthe70s.org/sslblacklist.aspx)
+* [Perspectives](http://www.cs.cmu.edu/~perspectives/firefox.html)
+* there is another firefox extension that basically disables all TLS certificate checking. The download page says things like "this is a bad idea" and "do not install this extension", but i'm unable to find it at the moment.
