Feels like there's a protocol missing: one that can be used by all parts of a persistent computing system without constraining the system as a whole

The protocol is OCapN

That's right! We are developing our own stack at Spritely but OCapN is a protocol to be implemented for any and all programming languages so we can have interoperable capability security over the network. Besides our Scheme implementation, there are JavaScript and Dart implementations in active development currently with hopefully many more to follow.
