I stumbled onto this websocket-rack github project which is basically a rackified em-websocket and actually got it to work nicely side-by-side with a Sinatra app. Here's my config.ru:

require 'rubygems'
require 'rack/websocket'
require 'sinatra/base'

class WebSocketApp < Rack::WebSocket::Application
  # ...
end

class SinatraApp < Sinatra::Base
  # ...
end

map '/ws' do
  run WebSocketApp.new
end

map '/' do
  run SinatraApp
end

Have fun!
