I'm still confused about the server-side roster. Is the roster entity that's managed by means of jabber:iq:roster queries the same thing as the current set of people whose presence I'm subscribed to? Or is it a separate entity that the client needs to manually keep in sync with subscribe requests?
That is, if I subscribe to someone's presence by sending <presence type=subscribe>, will the server automatically add them to my roster, or do I also need to send an <iq type=set> tag with a jabber:iq:roster query? (And ditto for unsubscribing?)
[The JPO and JPG authors might take note ... I consider this one of the most confusing aspects of Jabber so far. It deserves to be described in its own section, not just buried in a discussion of the XML schema for jabber:iq:roster.]
Thanks,
