Very interesting, I have a few questions about this.

Is this feature still going to require providing name, dob, country of residence etc to primal, as setting up the wallet does now?

Is is there some central server like a primal server needed to get this to work? Or is it relays and ecash mints only?

Thanks. 

 If it was bound to primal, it's worthless 😕 

 Relays and ecash mints only.  

 so Relay disappears. Ecash gone?? 

 All must disappear at the same time; I have the concept of “relays health” on each token so that can always keep copies in n relays
