gevent-socketio is a Python implementation of the Socket.IO protocol, developed originally for Node.js by LearnBoost and then ported to other languages. Socket.IO enables real-time web communications between a browser and a server, using a WebSocket-like API. One aim of this project is to provide a single gevent-based API that works across the different WSGI-based web frameworks out there (Pyramid, Pylons, Flask, web2py, Django, etc…). https://pypi.python.org/pypi/gevent-socketio/

HTML5标准里有一个支持全双工通信的技术，叫WebSocket，也就是说可以由服务器高效率低消耗（相对于Comet技术之类的）地向浏览器推送数据，也可以由浏览器向服务器发送数据。
那么，在支持HTML5的浏览器上，你可以写一个js脚本，用WebSocket接受服务器发送的数据，在Python上，已经有Flask-SocketIO这种可以利用WebSocket的扩展了。

你可以试试这个gevent-socketio.

我尝试web2py + gevent-socketio。
