Take a look at multipart/x-mixed-replace for HTTP server push. Dug's msgbus (http://code.google.com/p/msgbus/) is an pub/sub implementation of multipart/x-mixed-replace that uses libevent/pyevent. The current state in SVN is not very buildable, but I can provide you with a working tree off-list if you're interested.
