Don't try to forward messages to their destination. Instead, forward them to several sites distributed around the net, and folks can check their messages via the net from whatever site is closest to them. I would suggest using public keys in lieue of MAC addresses, and Shamir sharing really sensitive stuff. ------------------------------------------------------------------------ Stuart W.
