Proxy for Amazon Cloud Drive

This is “somewhat” working for me … but extremely slow speeds; <100 kbps on a 1gbps connection.

-vv shows:

DEBUG : pacer: low level retry 2/10 (error HTTP code 400: "400 Bad Request": response body: "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<Error><Code>InvalidArgument</Code><Message>Only one auth mechanism allowed; only the X-Amz-Algorithm query parameter, Signature query string parameter or the Authorization header should be specified</Message><ArgumentName>Authorization</ArgumentName><ArgumentValue>Bearer Atza|...</ArgumentValue><RequestId>...</RequestId><HostId>...</HostId></Error>")

Any way to speed this up?
