That's easy ! And it has nothing to do with whatever language you use. It
does it requires to write a JSM module as long as your component is only
meant to process the received packets and not interfere with the JSM
processing. This can be applied to build a kind of packet "sniffer" and
allow you to count, record, monitor, etc...

You just need to declare a service in your jabber.xml so to receive a copy
of all packets going through the server.

<service id="sniffer.myserver">
  plus any aother internal JID that you want to monitor


Then the sniffer component will receive a copy of all traffic for the
<host>s. The component can sit on another server as any component can.

There is no way that I jnow of to separate the packets types before they are
sent to the component. But you can either make one component per packet type
and filter the input, or make a filter component that in turn direct the
right packet type to a specific processor component.

Hope it helps
