  Primary reasoning being the export restrictions..  No, raw packets would not be encrypted, merely the data WITHIN those packets..

  Already done in the base jabber system..  This information is NOT presented unless you are both on each others lists..

  Again, already complete.  The server side has 'security settings' for personally stored data on the server, aka, who can access what data..

  This is where we would have to extend our current digisig module to actually encrypt the message text, vs just signing it.

  As far as I can tell, the only place we seem to part company is the level of encrypting EVERYTHING that goes thru..  Some things we simply cannot encrypt, since we are building a modular system that can communicate with other systems as well as ours.  We could not really have encryption happen for the entire proccess for a converation between a jabber user and an AIM or ICQ user.

  I can throw it someplace tonight that they can link to, and let you know..
