[jdev] mirroring many presence servers

If you know the language that your server is written in you could catch
all the presence notifications before sending them on and store them
locally (in your database etc.).

However, what you are asking kinda doesn't make sense. If you never get
a presence notification from a contact, they *are* offline (if you
notice, while your client is connecting to a Jabber server all your
contacts briefly show as offline), unless you are not subscribed to
them, in which case you would never know anyway.

Hope this helps.
