Opportunistic Encryption of IP traffic: FreeS/WAN 2.0

Russ Nelson writes "Since 1996, John Gilmore has dreamed of an Internet where all traffic between cooperating sites is encrypted. He has supported the FreeS/WAN project which uses IPSEC to encrypt IP traffic on an opportunistic encrypting basis. The team has released Linux FreeS/WAN 2.00, their first release optimized for Opportunistic Encryption (OE). After installation, ZERO host configuration is required for OE! A Linux box running 2.00 will encrypt all IP packets to other OE capable boxes whenever possible, provided you publish a key and IPsec gateway information in DNS." Nice.
