[zorp] Telnet data or UDP paquets?

To whom it may concern, Is there a way to look into telnet data part or udp packets and log or even filter that on some keysequences? I read in the documentation that telnet proxy only filters some telnet commands but not what the user types. This PlugProxy could also handle UDP and telnet trafic but seems like no use because it does only simply forward without doing anything? Can Anypy be used for this as I think telnet would need a no-blocking proxy and Anypy seems to block on read? Does Anypy handle UDP paquets, too? I hope anyone can help me here and sorry for my bad english! Sincerely Yours Clement Fillon
