Thanks -- After reading the paper I think I have a better understanding, and it is pretty exciting, this does seem to be a pretty good throughput improvement, especially if things are mostly happy-path.

The paper seemed to be missing an exploration of worst-case scenarios and equivalencies though, but I guess I guess worst case is paxos speed (consistently failing sequencer, or a leading replica that receives one messages then is unreachable, bad quorums, etc)
