I find this historical discussion interesting because it suggests some
very different vantage points.

My vantage point was close to John Day's.  I was at BBN (arrived in 1983)
and there were internal debates of TCP/IP vs. TP0/X.25 with the additional
twist that folks like John and Ross Callon were working to develop TP4/CLNP
to compete with TP0/X.25.

We had cheerful debates over CLNP vs. IP.  (I read a draft or two of the
CLNP specs for Ross -- which led to an odd statement later during the
protocol wars where I was asked if I'd read the CLNP spec and the answer,
honestly, was "no" -- I'd read the earlier drafts...  and I got pilloried for
commenting on CLNP without reading it that bit of stupidity on my part).

But the big fight was TCP/IP vs. TP0/X.25 (or, more truthfully, my recollection
was the fight was TCP vs. X.25 -- where to put the smarts...)
