The article http://errtheblog.com/posts/19-streaming-capistrano has a great solution for this. I just made a minor change so that it works in multiple server setup.

  desc "open remote console (only on the last machine from the :app roles)"
  task :console, :roles => :app do
    server = find_servers_for_task(current_task).last
    input = ''

    run "cd #{current_path} && ./script/console #{rails_env}", :hosts => server.host do |channel, stream, data|
      next if data.chomp == input.chomp || data.chomp == ''
      print data
      channel.send_data(input = $stdin.gets) if data =~ /^(>|\?)>/
    end
  end

the terminal you get is not really amazing though. If someone have some improvement that would make CTRL-D and CTRL-H or arrows working, please post it.
