I’d like to create a new real-time RSS feed using pubsubhubbub by processing an existing RSS feed which i cannot easily change. Is there a tool or approach which makes this easy? The RSS feed which i want to process does not offer pubsubhubbub links and i assume i have to poll every N seconds. Is there a readymade solution or example for this, preferably in Python? (In case you are interested i’d like to have a real-time feed of pypi.python.org updates, consumable by arbitrary other servers).

According to MvL’s slides of his talk at Zope Tagung 2010 (page 19) PyPI publishes the feed with the changes of the last hour on http://pubsubhubbub.appspot.com.
