Google is deprecating iGoogle’s shareable-prefs API & feature that enables gadgets to share state across multiple users' pages. In the next few weeks, iGoogle’ll remove the UI elements for shareable-prefs, preventing any new gadgets from implementing this feature. A few weeks later, iGoogle’ll break the links between these gadgets entirely, at which point, the gadgets’ll behave as if they were never shared. However, both users’ll retain the data in their preferences. The gadgets should continue to function in every other regard, but gadgets that wish to share data between users should implement OpenSocial's requestShareApp (paired with appdata, or a 3rd-party storage mechanism), announced.
