I would like: my communication point with the outside world to be run on a node in my house (like a start9). I'd never miss a communication; it's always on, I can set up an auto reply if I'm offline, and it runs securely on my own hardware. Then a second cryptographic structure between the node and whichever device(s) I am using at tbe time, each configureable as I see fit. This solves the multiple device problem - all communications come from my node, anything I write comes from there. However, I can control the node securely from whichever device I choose, and customise the terms, structure and communication methods between devices and node, according to my situation and threat model.

Somebody pick ho'es in this idea...
