Don't worry, /I/ don't do this.
Some large enterprise/campus networks do, though.
Let's revise my number to "2". Just as much as a problem if they're both trying to do proto-41 :-)
The other thing to note - 6to4 kicks in on Vista if it has a non- RFC1918 IPv4 address, so we're talking about people NATing large numbers of non-RFC1918 space. Regardless of how crazy they might seem, these networks exist, and they're preventing people from rolling out IPv6 (AAAA) to production stuff. It's annoying, because they're often the same people who say "I'm not going to pay attention to IPv6, I've got enough addresses.", and we all lose because of it. (That, or when those networks become few enough that we can turn on AAAA records for production stuff, they'll be forced to sort their stuff out).
