Simple Multiplayer game in Ruby on Rails?

Question

Hi guys,

I have created a simple card game in Ruby on Rails+ajax with jQuery for animation. It's working Ok, and I wanted to develop a multiplayer version. It looks like it's not so simple as i thought. I have also tryed to port the game completely to JS into the Canvas tag. This is possible for me and I could make the animation there much better however I still don't know how to add a multiplayer part in it :( Does anyone tryed to use websockets with rails already? This is pretty fancy new technology. Is it worthy to stick with rails at all? I wish i could start from scratch in flash but I don't have any knowledge in it :( Any advise or tutorial will be helpful

Thanks
