Abstract: Collaborative sessions, including website browsing sessions, are supported where particularized content of a first user is shared with a second user in order to synchronize a collaborative session attended by the first user and the second user. The particularized content may contain information generated during the session, information regarding previous sessions, and preferences indicated by a participant in the collaborative session or a system administrator. The particularized content may be synchronized on a peer-to-peer basis as well as through server intervention. The user for which the particularized content is targeted may maintain controls over when and to whom the particularized content may be shared.
