LARTC - Feb 2007 - CryptNET Peer Cache Daemon

Hi

Anyone has tested "CryptNET Peer Cache Daemon" ??
http://cryptnet.net/fsp/cpcd/


I''ve heared that by using a Peer Cache Daemon I can lower 
p2p traffic over my internet link, and provide better rates
over p2p downloads to LAN users.

I would like to know if somebody has tested it ...
is a Peer Cache server really useful   ?

Best regards,
Andres.
