He's been informed now at least! ;-)

It seems it does pretty much everything we need then, with the lack of IPv6
lookups as an exception. But I don't mind proceeding with adding support for
asynchrous lookups first for IPv4 addresses, and when we get that working we
can proceed and make ares grok IPv6 as well.
Of course, if someone else would make IPv6 work independently of my work on
getting libcurl to use ares, I'm fine with that too! ;-)

Neat. I've downloaded and built this ares-1.1.1-win32 package on my Linux box
and I've written a few example apps using it. It just works! ;-)
I'll also need to concentrate a bit to get the upcoming curl 7.10.6 release
out the door properly, so this work will be done a little "on the side". I
mean, apart from all my regular real-world work of course.
