Chizzle (3.0) is a ruby (and rails) ide that uses Ajax through a browser as the front end. To be successful, it must look and feel like a smart client.
The name is still up for research paper help debate.
For now, the svn repos is : svn+ssh://rubyforge.com/var/svn/chizzle/trunk/chizzle.ajax
and the stories are : ThoughtCoder.rb Stories
