I was under the impression that Apple might start to release some developer's info for iSync as the new Xcode and Tiger get close to release. Was there any news announced on this at the developer's conference?
The only thing I've seen on the Apple site was at the bottom of the page for .mac Sync: "System-wide availability of sync services means that developers can now easily incorporate syncing capabilities into their applications. Tiger’s sync engine is extendable, so developers can go beyond synchronizing calendars, bookmarks and contact lists." I hope this isn't just extendable for .mac, but for adding new devices to iSync.
