True. However, IP and UDP will have issues.

Over a year before any documents said anything about it. This is where I
have problems. :-)

That is a very good point. I've been talking v4 all the time (both for
IP and TCP). Like I said, I'm sure people were doing networking
protocols and stuff earlier, but it wasn't the TCP/IP we know and talk
about today, and you just reaffirmed this.
And yes, the TCP/IP we know today did not come out of a blue sky. Of
course it is based on earlier work. (Just do you don't have to go on
about that again.)

But not TCP4 then. And thus, not interoperable with an implementation
today, and interoperable in general being a rather floating and moving
target, as you had several imvompatible TCP versions, using different
protocol numbers, and several incompatible IP versions.

Fun times, I bet.
