Sorry, I don't know of any JEP that would help. You will probably have
to write it yourself. As I said:
* Client sends presence notification
* Your server "notices" the notification
* Your server stores this in the database
* Your server forwardes the original notification
You can also subscribing your sever. As far as I know, that should work,
but some other clients/servers might break if you try that. Maybe
someone else could elaborate (Peter)? I have noticed that websites (such
as the Jabber world map) need a contact in your contact list to
subscribe, I'm not sure if has occurred to anyone to just subscribe the
