Indeed. This is something I considered. But Rails support is growing more ubiquitous, particularly with the rise of VPSs. And even if a hosting provider doesn't explicitly support Rails, it's often possible to install Rails nonetheless. The biggest missing ingredient is a one-liner installer for all the dependencies. Installing Rails, the MySQL gem, and Passenger on a fresh server is not terribly hard for an experienced Unix user, but it is quite intimidating for casual users. So one of my goals for the project is to create a "worse is better" Rails installer. I.e. a really quick-and-dirty script, bundled with the CMS, which gives you a minimal Rails/Passenger/MySQL environment. It would be optimized for issue-free installation on a variety of hosts, rather than for bleeding edge features or maximum performance.
