Interesting, but middleboxes can scan for known unsalted versions and block some of these. This effectively stops these versions because salting isn’t reliable. Furthermore a middlebox can drop any initial packet it doesn’t understand to force unsalted version on retry.

It can still work for less aggressive middleboxes, but perhaps it is better to wait for the fully encrypted solution Kazuho and Huitema has been working on.
