Connecting to MS SQL server with Ruby on Rails

I've started to look at how I can connect to a database running on Microsoft SQL Server 2000 with the Ruby on Rails framework.

I have Ruby on Rails running under Apache on a RedHat Linux server, while the MS SQL instance is running on a Windows Server 2003 box on a different network. Needless to say, I have a unique environment for this project.

The goal is to rapidly build a fast web application which will tie into a back-end proprietary database.

Here's what I've found so far:
