I agree with your points. It is indeed a viable, if somewhat clunky solution.

For getting the data into S3, we found exponential improvements in using the AWS CLI, as I believe it handles uploads in a multi-threaded way.

S3fs turned out to be viable for our use case, storing Magento Enterprise content assets which are then served directly from S3, so the app's upload features rely on s3fs as well as the file checks from the app itself (which are indeed quite slow).

I've always wanted to do it natively, mounting EBS volumes on more than one instance (which is not currently possible) or wishing for a native NFS service like AWS released.

All in all, it is a happy day for me. More options make us more powerful.
