The version bits were asked for during the meeting on the basis that
IP's version number has allowed us a nice transition facility. I'm
unsure as to whether the version bits are valuable or not. I'd
personally like to hear some discussion of this.

I would tend to agree with that, too.

Remember that if we rig the negotation protocol right, most of the
important things get put in the negotated choice of security
transform. If it turns out that the way we are doing things now is
bad, we can likely just abandon the current security transforms over
time for new ones without changing the encapsulation at all.
