The state of syncing in open source — SyncEvolution documentation
Summary
Evolution Data Server was not the preferred PIM storage for MeeGo 1.2 until recently, so depending on it for CalDAV/CardDAV support was not an option. • None Capable devices by design store a complete copy of the data, without depending on one particular server to remain online. But then the client/server model **becomes** synchronization and must deal with the same kind of problems that it was meant to avoid, like conflicts between items on client and server. That doesn’t sound like a very useful approach, because users won’t be able to remember what changes might have been lost and if they do, would most likely be forced to redo them manually. PIM data is more complex then plain text, so the merge strategies that programers know how to use with source code and revision control systems do not apply.
