Re: [Mipshop] Gauging interest in official WG adoption of internetdrafts

[Rajeev Koodli <[e-mail]>]

The purpose of SEND-based key derivation for handover is to obtain a 
handover key for securing FMIP signaling (Primarily FBU). Whereas a 
general-purpose solution may be desirable, our experience with such 
efforts indicate the pitfalls associated with subtlety. So, I prefer to 
keep the scope of the _current_ WG item to securing FMIP signaling. 
Perhaps in the future, enhancements may be considered.
