+ * anytun
+ *
+ * The secure anycast tunneling protocol (satp) defines a protocol used
+ * for communication between any combination of unicast and anycast
+ * tunnel endpoints. It has less protocol overhead than IPSec in Tunnel
+ * mode and allows tunneling of every ETHER TYPE protocol (e.g.
+ * ethernet, ip, arp ...). satp directly includes cryptography and
+ * message authentication based on the methodes used by SRTP. It is
+ * intended to deliver a generic, scaleable and secure solution for
+ * tunneling and relaying of packets of any protocol.
