Today Amazon announced a file storage service meant to compete with Dropbox, Box et al.

I read the announcement looking for a clue as to whether Zocalo built on their strength in APIs, specifically the deeply entrenched Amazon S3 service. What if you can program your organization's file storage system using APIs that you already know? Few APIs are more familiar to more programmers than S3.

I sent an email to Amazon asking about this, haven't heard back. Curious if anyone knows.
