evserver - Google Code
by greutEvServer is a lightweight http server, created especially to host python WSGI applications. Additionally, it supports little known Asynchronous WSGI extension, which was suggested by Christopher Stawarz. Using this extension it's possible to create an output html response in many data chunks, without blocking the main server process while your application waits for external resources.
Comet the WSGI way.
