Ok, here's a twist. I'm researching The Great IDN Disclosure.
This is yet another tempest in a teapot you've probably never heard of.
My fellow Shmoo, Eric, found some cases where you could construct a
domain name that visually looked like one site (say, www.paypal.com)
when in fact it was some crazy mutated unicode domain name from dotdashistan
or something.

What do you do when you find an exploit in a protocol spec? Do you
disclose it to the standards body? Do you tell the vendor? Do you simply
announce it? If you tell the vendor, is it ok for the vendor to choose
to ignore you because they've faithfully implemented the standard and it's
Not Their Problem?

I guess my current allegedly interesting observation about disclosuers is -
if you notify a vendor, and they ignore you or go into denial, then well they've
just told you it's not an exploit and you can publish it whereever you damn
well please. (not that I've ever had Cisco or Microsoft deny I've found bugs,
oh, no, that'd never happen...)

And if you think it's off topic, remember that the more trouble we make with
primitive research tools, the more money we get to spend on copies of Canvas to
do real security testing.
