It would really be interesting to see something like a "personal SOLID server" that runs on your phone, and is reachable in IPv6 only (or through tunneling via "DNS for people", replacing phonebooks conceptually and handled as a separate distributed service). The biggest obstacle to running a personal server is that it must always be on, and always be connected. Using cell phones (which certainly have the capacity for most individuals) would make that easy, and also refocuses "my data" into a physical concept. When you used to unplug your phone, the entry in the phonebook would fail. Now, when you turn off your phone, you "go dark" in the truest sense. It would be very easy to have a secondary battery that powers a low power coprocessor optimized for this task so that even when your phone dies, the server lasts a while longer (say 48 hours?). I think ultimately if we're going to live in a world of personal data ownership in the truest sense, our data must be something tangible we can carry with us (and that isn't an extra thing to carry). Of course, you'd want to back up that server config and your data, so there would be monetized services for that. Celebrities and business owners would have substantially more traffic or need to be online all the time, and as a result would need to actually pay for hosting and maintenance as a function of their utility. This introduces yet another market. And throughout this whole system, you are now explicitly trusting your data as an object to a company for their services. You are not participating on their platform while they farm your interactions. Any thoughts or criticisms?
