That's were the work of Florian _really_ impressed me. See the 
command-line options:

$ ruby dispatch.servlet --help
Usage: ruby dispatch.servlet [options]

     -p, --port=port     Runs Rails on the specified port. Default: 3000
     -i, --index=controller  Specifies an index controller that requests 
for root will go to
			                (instead of congratulations screen).
     -d, --daemon        Make Rails run as a Daemon (only works if fork 
is available -- meaning on *nix).
     -a, --auto-reload   Auto-reloads all the classes on each request 
(use during development).

If you start the server with --auto-reload, each request will get its 
interpreter -- just like running as CGI! The server accomplishes this 
by instead of using its own interpreter, it'll boot a new one during 
request handling. Here's the juicy bit:

   IO.popen("ruby", "r+") do |ruby|
     ruby.puts <<-END
       require 'cgi'
       require 'stringio'
       env = #{env.inspect}
       CGI.send(:define_method, :env_table) { env }
       $stdin = StringIO.new(#{(req.body || "").inspect})

       Dir.chdir(#{@server_options[:server_root].inspect})

       eval(
	    'load "dispatch.rb"',
	    binding,
	    #{File.join(@server_options[:server_root], "dispatch.rb").inspect}
	  )
     END
     ruby.close_write
     data = ruby.read
   end

The Ruby license had a bunch of stuff specific to Ruby. MIT license is 
much simpler and very free. Have a look at 
http://www.rubyonrails.org/show/License for more.

You betcha! I just got my fancy Sony microphone hooked up, so the next 
videos will also have a voice over.  I'll be posting them to the newly 
established Rails Academy at
