Re: [MMUSIC] Unknown key shares in MMUSIC

One ID for both TLS and DTLS make sense to me. 

The one thing that is key for perc, is that in the Client Hello, this need to not be encrypted so that the MDD can use it to recognize which KDD is meant to be routed to. Effectively you can think as the MDD as a load balancers for all the KDDs that act as the TLS server and it is using this field much like a normal load balancer might use SNI. So I want to make sure we preserver this property. 

This is probably crazy, but, I wonder if it would make sense to just use the SNI.
