push data to any browser is difficult.
WebSocket is ok for mobile/chrome/firefox/safari, nok for ie
 thin demo there : https://gist.github.com/raubarede/5799539

   > gem install thin
   > gem install sinatra
   > gem install sinatra-websocket
   > ruby mouse.rb
   > open  http://localhost:4567
   > open  http://localhost:4567
   .. move the mouse in first page
   .. look what append in second page :)

At my knowledge, in enterprise context, socket.io with node.js is the 
only
universal (ready for almost all browsers) solution available
