feature request: redundant state computation

[Pyrolistical]

We need this: https://history.nasa.gov/computers/Ch4-4.html

we need to setup 3 service works with 3 different redux/state machine implementations, then 3 managers to that check the 3 pairs of results. if at least two managers agree with the result, then that is used.

this will allow this app to run in hostile environments
