Hi Chris, Yes, there are several. We host one of them at least. But they are not needed for peer-to-peer only for those cases when some users use Teredo and others have 6to4 or other IPv6 (native, other transition techniques). Of course, this situation will become more and more frequent (more people using IPv6, even w/o knowing, means more people using different transition mechanisms and having more chances to need to use 6to4 and Teredo Relays). That's why I'm trying to convince folks about deploying 6to4 and Teredo relays, which is something quite simple to do. Also this will allow to scale. For example, I guess that if a big ISP setup 6to4 relays in the same router that they have at every POP, then there is not an scalability issue, even if those relays are only available for the ISP customers. For Teredo, today you need to use either Windows 2003 or the Longhorn (which is a beta), or Miredo which can be setup in any Open Source OS, but I don't think is a big issue either. I expect the router vendors to have Teredo support in a short time, hopefully. In our case, we host a Teredo Server+Teredo Relay+6to4 Relay+Tunnel Broker in the same Linux box, which is also IPv6 natively connected to our dual-stack infrastructure. This is what I would recommend. In fact, because this becomes much more relevant were the upstream transit is more expensive, in LACNIC and AfriNIC (in Spanish an English, respectively), next week I will start a thread to explain how to install both in different platforms and solve problems that the people may have when doing so. Folks interested in the English version should subscribe at https://lists.afrinic.net/mailman/listinfo.cgi/afripv6-discuss. For Spanish subscribe at https://mail.lacnic.net/mailman/listinfo/lactf.
