Performance is not an issue when doing peer to peer with the same transition mechanism (example Teredo to Teredo or 6to4 to 6to4), actually the performance is better than doing it with IPv4 and using intermediate hosts, such as MSN or Skype do. Performance impacts when both hosts doing peer-to-peer (or client-to-server) are using different types of IPv6 connectivity (example, native vs. 6to4 or Teredo, or Teredo vs. 6to4). This is solved by deploying 6to4 and Teredo relays in the ISPs, and is actually something inexpensive that ISPs should do while they can't provide native access. Regards, Jordi

Agree with Florian and you. It is needed to say something to remind vendors that market is already asking for IPv6 support. I don't think they should just wait for the demand to come, because then it will be late. So a warning to them is a good thing. Same for software developers, they should realize that they can take advantage of IPv6 NOW, because even if there are no native access providers yet, transition is available in end-hosts.
there are NOT ENOUGH native (commercial) access providers ...but we should make a small note that some already exist. :-)
There is no immediate need for low costs CPEs, of course is good to have, but transition tools in end-hosts already deliver the same, until access
//transition tools in end-hosts//
...and what happens to performance???
imho, low-cost CPEs are key if one wants to seriously see IPv6 deployed significantly. it would be a significant contribution to break chicken/egg-type problems...
providers provide dual stack, then of course, CPEs with allow dual stack on the WAN link are needed.
