* write better documentation * Adapt it to IPv6 - better yet, any protocol. * this would require to base routing on MAC addresses instead of IP addresses, as is done now. If this can be done, IPX is also supported. * let tinc assign a MAC address to the tap device, based on some whacky number * add a digital signature to each packet, using HMAC * enable encryption using other ciphers (IDEA) * the library is already included, but it cannot be used. * allow multiple outgoing links, or a list of them, so that if a host is not available, that we can select another from the list. * support for multiple protocols; PPTP, IPSec, NIAS, L2TP,...
