Brian,
I'm finding that I'm being misquoted, and I don't find it very funny.
I did not call myself an honorary CCIE. What I actually said was that
before the CCIE program, and before there were training partners
(roughly pre-1995), Cisco had a limited number of CCSIs. Most of
these were Cisco employees. The qualification procedure was NOT for
ICND, which didn't exist at the time.
I'm not the only individual to go back to this time frame, who has
NEVER called themselves an honorary CCIE but has not felt any driving
need to prove a point by having one. I think Priscilla Oppenheimer
can make some comments in this area as well.
Not on this list, but people I can think of who are not CCIEs,
include Tony Li, Yakov Rekhter, Dave Katz, JJ Garcia-Luna-Alceves,
Randy Bush, Andrew Partan, Radia Perlman, Paul Ferguson, Vint Cerf,
Scott Bradner, Frank Kastenholz, Karl Auerbach, Sue Hares, Sean
Doran, and many others. Do you know who they are? Do they know who
you are? Are you saying they don't know how to network?

The _current_ ICND. Indeed, I contributed content to or was on the
internal review team for, a fair number of Cisco courses.

And I know many CCIEs who couldn't design a really large network. So what?

Someone who thinks this isn't a problem has not had to deal with
Cisco's intellectual property attorneys. I don't propose to get into
the details of this, but I think Paul Borghese, among others, can
testify there are significant sensitivities.
