Wow - Nodes on smartphones is the final frontier for decentralisation - I did not expect to see that any time soon, great!
My only comment is that having recently built a new front end for hive (Ureka.Social), I found that locating the best API calls to use for various requirements to be difficult. Different servers support different calls and there isn't proper documentation (at least that i can find). It would be huge to have up to date docs (that are kept up to date) on which API calls are available on which servers, which are recommended.. and why.
