The best friend because it does indeed enable app developers to develop IPv6-only apps before IPv6 is largely deployed at ISPs. The worst enemy because if IPv6-only apps work good enough over Teredo, consumers will no scream bloody murder to their ISPs to get native IPv6 and stick to IPv4. This is _not_ a criticism, but you above everyone else should understand that one if not _the_ primary functions of Teredo is NAT traversal, and if it does break the chicken-and-egg problem between ISPs and app developers it does create its own chicken-and-egg problem which basically the following: it enables IPv6 on the desktop without an infrastructure, but OTOH it enhances IPv4 NAT which in turn delays IPv6 deployment.
