The problem isn't so much that it happened, but why/how. Many would have
expected better...but it is quite likely that this threat, like the source
of many other security "problems" (as opposed to bugs) is what customers
at some stage have asked for and now expect, so taking it "out" isn't that
easy.

Too bad this email virus wasn't ready on January the 1st, then people
would have had the "doomsday" they were all expecting. Even then, it only
becomes active when people read it, so roll forward to when ppl started
work in January.

Who knows ? But that's what we got when MIME came into being. Many Unix
mail agents run shell scripts to handle MIME and there have been a few
security issues there as well. Difference is that Unix mail readers don't
make up a majority of mail clients used by people around the world.
If you want real doomsaying, picture this - a Y2K version of the Morris
worm, exploiting the latest buffer overflows to propogate and install
DoS agents everywhere it goes and then at some predetermined time, start
flooding the 'net with random packets. It the post mortem analysis, the
source hosts would all be poorly secured Unix boxes (Linux/Solaris, etc)
and copies of a modified version of mstream to blame. What scares me is
that it's hard to know the real potential for that to turn into reality,
with perhaps our saving grace being that the people who could/would make
such a tool have to use the same 'net as us and therefore don't want to
do too much damage (or have too much fun). Back in the mid to early 90s,
as the 'net turned into a receiver pays for bandwidth system (and still
is to some extent), some of us theorised about these sort of attacks. I
am not sure I want to be around the 'net in another 5 years if there are
no real advances made with deploying and using RSVP for normal traffic.

Err, don't you mean the 'net is clogged with email rather than porn ?
