Ruby on Rails integration with MailChimp

The folks at ProjectLocker.com have created a way to integrate MailChimp with Ruby on Rails applications. It's open source, and posted at:

http://rubyforge.org/projects/ruby-mailchimp/

They've even got it checking an inbox for MailChimp's automated "This user has just subscribed/unsubscribed" email alerts, so they can take appropriate actions on their own hosted database.

Thanks, ProjectLocker!
