Thanks, Raphael!  I will be there, and = looking forward to getting interop.

To be concrete about the interop = target: In between now and the hackathon, I'm going to work on getting = mlspp updated to support the just-published -02 draft.

It seems like we can = probably build a ladder of test cases and work up:
- = Generate and parse UserInitKeys from one stack to another
- Create a two-member group by sending = Welcome and Add messages from one stack to another
- = Send updates within the two-member group
- = etc.

What = ciphersuite(s) are you targeting?  IIRC, mlspp only does the P-256 = one right now, but could probably be made to do Curve25519.
