Hi Jeon,
You are missing something.
Here is a link at the slides from the presentation I held at VON, San
Jose this year - http://www.slideshare.net/alwaysoncarl/vamanu-anca/ (
we will put it on our site also).
At page 24 there is a scheme with how RLS works.
It interacts with the client by receiving a Subscribe to a list and
sending it an aggregate Notify.
To get the info to put in the Notify it sends Notifies for each buddy in
list to the presence server ( where the clients have sent Publish
messages). The server will then reply with Notifies that will be
processed with rls_handle_notify function.
regards,
Anca
