1. Creating an Akonadi resource for the plasmoids
2. running Network status notifier to see if connection is available
3. If not then show the data in Akonadi cache.
4. If yes then access data sources using Akonadi capabilities.
Right ?

What about the collaborative caching part ? Do you think that accessing data
from other client's cache would be useful ?

Thank You
