This second part, having your notes and jottings and sketches updated onto the cloud shouldn't be that hard though? A site with an account, and then some functionality added to liqbase or maemopad+ to just upload anything new whenever they find an internet connection. Of course, someone needs to be build and host the site, and come up with a standardized format for the items to store, but it's nothing too technically challenging.

I'd love an app like that, and would easily pay a subscription fee. Or if someone does the maemo parts, I'll build the website
