I'd page Ross Callon for this one (he did CLNP and as I recall did a lot on
TP4 as well). Also John Burruss and Lyman Chapin comes to mind (perhaps
>ii) where did XTP end up
Around a surprisingly long time -- my colleague, Tim Strayer, who produced
that well-written XTP book while a grad student (!), was still fielding
questions from implementors into the late 1990s -- probably still is.

There was the CSNET nameserver (and there was a paper on it around 1984).
There was also a wonderful private debate c. 1986 about whether the DNS
approach was right, or whether a replicated central database into which you
registered would scale better. As I recall, a lot of the debate centered
on estimates of the relative cost of bandwidth -- those who argued for
centralization said, hey the revolution has to come (and it did c. 1989),
while those who argued for DNS said, don't count on it. [I should hasten
to add that my recollection is that the debate was not so much should we toss
the DNS, but a way to ask if the DNS design correctly reflected the future
and if not, were there things we could do to adjust the trajectory to make
it perform better].
