I'm thinking aloud here..
A p2p protocol, where each identity have at least 5 authenticating signatures, so that adding a new device/node to be used by an identity would just be replacing a signature, instead of adding one.
This would be for the purpose of masking how many nodes / devices are active for any given identity.
Hm. This probably needs more thought. There might also be something valuable in having two levels of auth, like DNSSec.
