Next to that... teredo and 6to4 are non-managed services, while 6rd is a managed service... big difference for the user experience.

Descending to 100m, one can see that, unlike Teredo and 6to4, 6rd provides native IPv6 prefixes to customer sites, unlike Teredo and 6to4:
- Hosts behind a 6rd CPE are on a dual-stack LAN, and can't determine whether the ISP network is dual stack throughout or 6rd.
- From 6rd sites, connectivity with other IPv6 native addresses is guaranteed, which is the case with neither Teredo nor 6to4.

You told me once that, for you, "hack" had no negative connotation.
Then, "cute hack" can nicely be taken positively, thanks ;-).
