Riding Rails: Introducing Rails Metal
Rails Edge introduces Rails Metal, based on Rack. Think of it as a way to bypass the Rails framework on certain requests. DHH gives the example of the Campfire chat application. I'm thinking about Flash Remoting (AMF). No reason to really call a controller, walk through the Rails stack, just to have separate logic query the database and return a serialized object. This could make Remoting through Ruby really really fast.<a href='http://weblog.rubyonrails.org/2008/12/17/introducing-rails-metal'>Riding Rails: Introducing Rails Metal</a>.
