 - redirproxy should pass out of band messages

 - redirproxy should accept command line arguments for the
   programs it runs

 - redirproxy should run an authentication script which should
   decide whether to accept or divert the connection.
 
 - redirproxy (or a derivative) should allow you to filter the
   incoming or outgoing TCP stream.

 - fakepop could be more funny / serious (via a command line
   switch??)  SSL support may be useful.

 - a fake imapd server would be cute.
