To have real time chat you MUST have javascript or flash.
Well, technically that isn't true but the other option is constant refreshes that will give most people a seizure and break the requirement of "A smooth chat experience"
HTML is not "smart" enough to handle chat on its own, and PHP doesn't have the client side access necessary for chat.
Essentially the closest you can get to a Chat Room script with the PHP/HTML only requirement would be a Forum. It satisfies all of your requirements but some use JavaScript.
Why are you so opposed to JS?
