Amazon S3 / streaming HTTP upload

[Anton Krasovsky]

I'm looking for a way to upload/download largish binary files
(photos/videos) to Amazon S3.

Thanks to streaming option in inets http client, downloading these
files seems pretty straitforward.
However uploading to S3 is more problematic because streaming is not
supported for put/post requests
and entire file has to be read into memory before I can post it.

Would anyone know about http client/Amazon S3 library that would work
without buffering of the entire file?

Regards,
Anton
