One of the coolest features of Vista is the ability to browse remote repositories using Jabber to convey the necessary data and meta-data. It uses Jabber extension messages to determine what views are accessible to the requestor, and to request and receive the relevant data items, via a simple UI described in the next section. More sophisticated users can address remote views and data items directly, by typing a URL that has a Jabber ID at the beginning, as described above.
