Just a couple of announcements about my Ruby on Rails server image for EC2:
There is a new server image with some minor changes and bug fixes. For details see the change log. I'll keep the old image around for a while.
I'm working on a build script so the image can be built from source. Then I will provide access to a subversion repository with the source. Some people have expressed an interest in contributing, which I'm really happy about! If you want to get involved, please join the mailing list!
