Really? Since when? (Although, after writing this, I do recall seeing a
third-party analytics program that could spit out iOS details, but only
iOS... and i freaked out when i saw that too.)

I recall a number of years ago at a CSUN (back in the LAX days) where the
president of Freedom Scientific explicitly stated that they would be
opposed to anything like that, and would actively block attempts at doing
that. Additionally, this is not a new request, yet this is the first time I
am hearing that you can actually target AT (outside of the hoary old Flash
test of years ago). Jon, can you point this list to further reading /
resources about this please?

Like others who have chimed in, there are serious security and privacy
considerations that need to be contemplated here. Additionally, sniffing
for a screen reader (for example) doesn't mean that the end user is
actually using the screen reader themselves (it may be a shared machine,
where 1/2 of a "couple" need a screen reader, the other doesn't), or
situations where both sighted and non-sighted users are looking at the same
web page together at the same time. Thus, the presence of AT alone is
meaningless, and attempts in using that data to modify the user-experience
will likely fail as often as succeed.

In short, IMHO this is a really bad idea.

Agreed! What's the old New Yorker cartoon? "On the internet, nobody knows
you are a dog"? This is not a bad thing!
