This is massive news for any developers that were considering adding a sync feature to their apps. Even just local sync is a headache to implement from scratch, to say nothing of cloud sync – and what Apple just announced is a complete, unified solution from system-level APIs to servers, all ready-made and awaiting some Cocoa calls.

(And not to gloat, but I pretty much called this a week ago: http://news.ycombinator.com/item?id=2603921 )

Who wasn't calling it?

Android has had this feature for over a year. Shocking, right? This is what Diaspora should have been at the base. (Note, Camlistore might be interesting for those interested in these sorts of things)
