This looks like a nice initiative for application scenarios which you mentioned (like flying in a plane and needing the app to run).
My question from that view was, how would SQL Everywhere support distributed apps (with a centralized database?). Correct me if I am wrong, is SQL Everywhere targeted only for 1-to-1 scenarios between an app and an database? What if both you and me are on a plane, and running the same app and making local changes to our copies of database (either to disk or in-memory). Would there be an options to 'synch' our copies later on?
