Ruby and Rails supported on 10gen

http://www.10gen.com/blog/2008/12/ruby-support-on-10gen

It's official: the 10gen open source cloud computing platform (http://www.10gen.com) now supports Ruby and Rails. See the blog post for details and links to documentation, the SDK, mailing lists, and more.

The 10gen platform includes a multilingual app server and distributed document database. You can grab the source or download a pre-built SDKs from the Web site.

Note: the Rails support does not yet include ActiveRecord. We're working on it. In the mean time, you can access the database via an AR-like set of classes or "raw".
