Here is another approach, taken by Sam Ruby:
http://www.intertwingly.net/code/mombo/extractor.py
http://www.intertwingly.net/code/mombo/pingback.py

Extractor defines an html class that does feed autodiscovery. The
Pingback server then uses this class on the source URI to find the
feed's URI, and does a getElementsByTags('entry') in order to find the
entry that does link to the target URI.
It's a little awkward and may not work for all situations though,
especially one when a source document doesn't specify/have a feed.
