+Mongrel2 + wsgid
+----------------
+
+Mongrel2 is an application, language, and network architecture agnostic web server. It uses a high performance queue (zeromq) to communicate
+with you applications, all asynchronously. There is a well defined protocol to be used between mongrel2 and a backend handler (your app).
+
+Wsgid is a generic mongrel2 handler that speaks both mongrel2 protocol and WSGI. This makes it possible to run your python webapp written with any
+WSGI compliant framework. Wsgid has built-in Django support but has also a generic way to load your WSGI application object directly. It's possible
+to add support for other frameworks through wsgid's pluggable Apploading interface.
+
+To know more about mongrel2 and wsgid go to: http://mongrel2.org and http://wsgid.com
+
+There is also a tutorial about deploying Django using this stack: http://daltonmatos.wordpress.com/2011/11/06/deploying-your-django-application-with-mongrel2-and-wsgid/
