Oh, that's interesting! I speculated about sync and the iCloud a few weeks ago (http://www.hardturm.ch/luz/2011/06/icloud-sync-speculation/), based on a IETF draft proposal from early 2011, co-authored by Cyrus Daboo at Apple: http://datatracker.ietf.org/doc/draft-daboo-webdav-sync. Cyrus Daboo is the author of Mulberry IMAP client (now opensource, http://www.mulberrymail.com/download.shtml), who joined Apple some 3 or 4 yeras ago. Now I see that the CTag extension (from 2007) is also his work. Which makes - at least for me - an interesting picture, showing that Apple is working for some years now to make CalDAV, and with the new proposal WebDAV in general, a sync-enabled infrastructure. Although the iCloud itself is all but "open", it will certainly fuel the "sync" topic in general in the next few months. And if it is based on syncable WebDAV as I believe it is, that would be an important step towards open standards based sync! I hope such general thoughts on sync are not considere OT for the Syncevolution list :-) Lukas _______________________________________________ SyncEvolution mailing list [email protected] http://lists.syncevolution.org/listinfo/syncevolution
