We're rapidly approaching that point where judge, jury and
executioner are completely automated. As such neither scaling issues
of Stasi (at some point some half of the population were informants)
nor quis custodiet are a problem.

IIRC there's already collection on three degrees of separation 
in place, and that is already a fair fraction of the global
population so at least part of the judging is already automated.

How badly bitrotted is the codebase? With the current threat model
it looks like high-latency anonymous networks could well use a 
revival.
