It seems that you are describing a remote server now, which would be the same case independent on whether the local service would run in the user session or as a system service, no? > > > Obviously this was my petitions :), I'm not interested at all in > > > Akonadi, > > > is old computing too for people who works in only one computer, and I > > > > can't > > > > > share my Nepomuk's data with all my devices so I think a software > > > > developed > > > > > in 2013 supports 2013 software requirements. > > > > I think you might have some misconceptions about Akonadi but you are > > welcome > > to proof me wrong :) > > > > Probably, when Akonady has a check to disable it maybe I change my mind > > ;). Which neatly proofs my point about misconceptions :) Akonadi is started on a need basis by its clients. In order to "disable" it you simply don't use any of its clients (which would be useless anyway without data). > > A uniform and data type agnostic access layer sounds pretty state of the > > art > > to me. > > Yes, but a single user one running in your user session and not as a > service when you don't want it not. Not quite understanding your "but". It is exactly running in a user session, as a service, and not running when you don't want to. > With so many years of development I'm > assuming Akonadi works well for a single user in a single user computer > with only one session opened :).

Depends on how your search is implemented and how your data is stored. If all that email is local then accessing the data should be a problem. Might be more efficient when indexed but not necessarily mandatory, If all that email is on an IMAP server, search could be delegated to it when the server is reachable and fall back to whatever is currently cached when not. > In my case I have a tablet, two mobiles (Android and iPhone), and four > computers (one in my job) so I need all this data synchronized in 7 devices > or this metadata is useless because is not reliable.

And that is orthogonal to a local service for providing access to the user's applications how? As far as I can see it would only be benefitial if only one program would cause network traffic for every single data interaction, especially in the 3G case.
