Hi,

I want to make one high level comments on the proposed charter for SFRAME. 

The charter attempts to be transport agnostic. However, we know there are
certain use cases this solution needs to support. And I think one of the hardest
from a security perspective is the multi-party centralised one with one or more
SFUs. Based on the significant discussion we had in PERC around threat model, I
think this charter do need to have in its description work to explicitly develop
the threat model as well describe which aspects of the threat model that one can
address. For example I think the security threat of media delay which is an
interesting variant of "replay" attack that exist for real-time media
conversation where there are logic that selects what to forward. 

Cheers

Magnus Westerlund
