Both Node.js and Tornado seem to have scaled for real-time-web stuff in the past: http://news.ycombinator.com/item?id=1088699 http://news.ycombinator.com/item?id=1088699 http://friendfeed.com/ http://friendfeed.com/ I think I'd try Tornado first myself because of Python's error tracebacks. In my opinion they make debugging significantly easier. Is there any other software in this space?
