This is great news. I've been using goamz for some coreOS presence/sidekick containers, but found it quite lacking in quality, with a lot of missing functionality. The ability to build a container that clocks in at under 10MB (vs ~700MB for a ruby aws-sdk stack) based on a minimal busybox container and a standalone go binary makes it an ideal use case for presence or short-running cron-type containers. Also, the quality of the existing AWS sdk clients (especially with the most recent major versions) has been excellent (at least in my experience with the ruby and PHP libraries).
