Well, both Kolab (which has an imap server inside) and an imap server share 
the same problem: you need a machine that is permanently online. I cannot 
have it (well, technically I could, but I don't want to run 24/24h a 
computer just for this).

The solution should be much simpler:
1) fix the maildir resource so its folders can be shared/used by other apps 
and if mails appear there, it will realize that and import them (and the 
status info) to the akonadi db
2) make it possible to set the server completely to offline mode - or put 
the offline to online warning into the "server" code, you get a warning no 
matter which application tries to turn them online.
3) 2-3 is already enough as a start, but a way to export/import the metadata 
from akonadi would be nice. I'm not sure how this could be implemented 
realibly though.

Then it remains the "problem" with the local IMAP cache, which used to be a 
maildir folder, but this is less an issue, as IMAP data is on the server 
anyway, so the sync can go through the IMAP server. The only annoyance is a 
need for an extra IMAP sync after the local sync.

What is your opininion (especially Volker's, and others who worked on 
akonadi and the resources), is this feasable?
