Hi, guys.

Currently, the s3 cachestore does what it says it does: persist to S3 ;)

That said, the next beta of jclouds  supports 5+ storage clouds:
s3, rackspace, cloudlayer, nirvanix, microsoft azure, and anyone running mezeo v2.

Is we interested in adding multi-cloud support instead of or in addition to s3?

What do you think?
