+ new component
The ECMH stuff is really cool, I'm cautiously optimistic this is going to be great!
How about Pod and Cell? I.e. a Pod with 10 members each having their own Cell. Or perhaps Enclave and Chamber?
I think this is kinda real though, people that don't rely on turn by turn navigation tend to have a much better sense of direction IME
MLS makes rotation fairly cheap, i.e. removing someone from a group is O(log n) complexity.
HMAC would require everyone in the bucket to agree to the same key, so you would likely need a GKA protocol like MLS, right?
What a comeback!
