There can be no new layer 4 protocols due to NAT. You have to use either TCP or UDP.

  So instead of doing things properly, we'll hack around it... Isn't that what we're all complaining about? Let's do it right and then fix NAT

  So we can move from IPv4 to IPv6 but not introduce a new transport because of NAT? Hmm...

    The IPv6 transition is not going that much better than SCTP. So many people have v4-only home routers that they have no plans to ever upgrade.

      Most people have a free router from their ISP, the ISP will just send out new ones

      My ISPs modem has a built in NAT that can't be disabled, but it still passes all IPv4 packets through in DMZ mode, so there's hope.
