[JDEV] Re:Creating a presence server component?

[Philippe Raxhon]

I now remember another solution. In the jsm section of jabber.xml, one 
can add:
<archive>
  <service>myservice.myhost</service>
<archive>

given you have defined such a service in the service section of 
jabber.xml, for instance:
<service id ="myservice">
  <host>myservice.myhost>
  <accept>
     <ip>localhost</ip>
     <port>5999</port>
     <secret>secret</secret>
  </accept>
</service>

The accept component (it can be writen in any language and doesn't have 
to run on the same host) will receive a copy of every message sent by 
the users. The interesting part is that I think it's easy to hack the 
mod_log module to "archive" not only the messages, but also the presence 
or iq.

Please, correct me if I'm wrong.
