My understanding is that some peer to peer apps are explicitly using Teredo, because it gives them some amount of NAT traversal "for free".
>>What exactly Win7/Win8 software prefer v4<->v4?
Chris's statement about preference is correct for apps which do not explicitly specify, what interface/address they want to use - e.g. user doing web browsing and the browser using mainstream Windows networking APIs to make a connection.

What exactly Win7/Win8 software prefer v4<->v4? I see a lot of BitTorrent traffic from Win7/WinXP preferring 6to4<->teredo.
Kiev, Ukraine. We have 14(fourteen!!!) ISPs in one house providing 100mbps for $12/mo or 1000mbps for $20/mo.
And to differ from that mob, we have to do something really different.
For example, provide a native IPv6 while other don't. So may be a monopoly is not so bad for a slow lazy business... :)
