For further reading on these topics see the book that just came out: "Inconsistency Robustness", editors Carl Hewitt and John Woods. It's a collection of 14 papers presented at two Symposia at Stanford in 2011 and 2014. Five papers are by Carl. Now available at Amazon.
I think that cyberlocalism is a bad idea.Information integrity and accessibility might seem better served by localizing personal information in devices, but the reality of ongoing and nondeterministic device replacement (such as how we replace our cellphones with a new model every so often), would drive data to the centralized servers and datacentrism would result. IMHO, it would be better to work toward Agent systems that are distributed to perform the tasks that Carl is discussing for Islets. Additionally, Agents can perform other functions such as Identity and Authentication proxies.
Carl answers this problem with the mention of using distributed implementations. So far I don't see a discussion of how the security of the Islets is maintained.
