Wolfgang has just send me a really nice HOWTO documentation
for the security framework, it should be online soon ...

The command line examples should work with PtP as well, just try a QoS
similat to:

<qos>
   <destination queryType='EXACT' forceQueuing='true'>
       joe
  </destination>
  <destination>
       Tim
   </destination>
</qos>

instead of the empty <qos/>.
(joe and Tim must be other clients which have logged in under this name).
