"The Amazon S3 REST API uses a custom HTTP scheme based on a keyed-HMAC 
(Hash Message Authentication Code) for authentication."

Oh bugger.

So a custom authentication scheme that curl doesn't support then? :-P

"To authenticate a request, you first concatenate selected elements of 
the request to form a string. You then use your AWS Secret Access Key to 
calculate the HMAC of that string."

Hmm, great...

Oh, and it appears to use SHA-1 rather than MD5. I wonder if anybody has 
binary implementations of SHA-1 that work on Windoze? *sigh*
