Do you have the numbers to back that up?

Your page mentions uploads to S3 - do you do regional matching with appropriate region buckets? I've seen numbers that are sub 1Mbps when you hit the wrong S3 region yet I can reliably hit 900Kbps - 1.2Mbps, if not faster at times, with Dropbox.

Can you provide some average upload speeds you've seen? (Even from a non-residential connection is fine.)

Also - you state unlimited size, but even multipart upload to S3 claims a 5 TB max object size limit. Did you work around that somehow?
