Yes, I found that page, along with this one:

http://www.xertech.net/Tech/CuCl_ech.html

which appear to be the two primary sources on CuCl2.  Everything else
I found is more or less a re-hash of what is in those two documents.
However, neither of of these documents mention the high-speed initial
production of CuCl2 (or high-speed etching) when using strong H2O2.  I
was able to find very little reference to this on the web, and what I
did find did not seem to cover the experiences I described in my
previous post.

I did do some searching of the archives, but Yahoo's search isn't the
best and it is painful to try to follow a thread.  In the past, I have
used a script to download the complete archives of Yahoo mailing
lists, build sensible message threads, and then search locally, but
unfortunately Yahoo's recent changes have broken that script.  In any
case, I was able to find plenty of references to CuCl2 etching, but
was unable to find anything that covered what I was talking about.
