There is.

It is at present just Amazon. Tho I've been noodling around writing
an Apache module that implements the server side.

In it's defense, the patch is pretty small, and I believe that Amazon
AWS is going to get big. And having it in libcurl will make more
people use it.

I will do that. The tricky bit is that since AWS transfer is not free
(20c/GiB), someone will need an AWS account to run the test.

I think I check for OpenSSL in the, but I will review
that part.

Mark Atwood                 When you do things right, people won't be sure         you've done anything at all.
