Sync S3 buckets in parallel mode via concurrent threads

A week back I realized one of my core S3 buckets at work (which we use for all a bunch of app uploads that are always needed) was a us-west-2 only bucket and not US-Standard. (Dont like that, When S3 gives you 11 9s why not get a US Standard bucket???). Considering that we had varnish in multiple regions with this bucket as the backend, I wanted to do two things -

1. Migrate all data from this bucket to a US-Standard bucket

2. Migrate all data from this bucket to a EU/Ireland bucket as well (coz I have app servers etc out there as well which need the same data – Did’nt want to come across the pond for every object we had to retrieve). Why? Reduced latency and reduced B/W costs (costs nothing when a EC2 instance in EU has to pull an object from a EU bucket).
