Allows for simple copying/syncing of buckets/keys across S3 accounts.
Allows automatic ACL modification where it is required (allow READ etc).
It's also multi-threaded so we can deal with big big buckets.
Get started:
$ git clone http://github.com/uhjish/bucketbrigade
$ cd bucketbrigade
$ python setup.py install
$ b2b.py --help
Look at sync_example.job for an idea of how a sync job can be setup.
We use this to set up crons and to sync production to devel etc.
Client/Provider gives you access to a bucket with key, secret-key but you need to get their CanonicalID to start mucking around with ACLs

Not the happiest most idealist place, but hey it works.
