Adobe's Christopher Haupt and Chris Bailey were accepted to speak about Adobe Apollo and Ruby on Rails at the 2007 RailsConf in Portland, OR. The conference runs from May 17th to the 20th. If you're interested in Ruby on Rails and Adobe Apollo, then you should attend their session.

If you're interested in Ruby on Rails and how you can use it to build sexy rich Internet applications, then you should join the Ruby on Rails RIA mailing list at Google Groups, or download the open source Ruby on Rails RIA SDK by Adobe to see examples of Flex and Rails working together.
