Viewing application errors in your favorite feed aggregator

Matthew stumbled over a cool blog entry by Raphael Stolt.
Raphael describes a very elegant way of converting his Zend Framework-based application's log into an RSS feed. What's particularly nice about this posting is that it's a small enough example so that on one hand it's easy to digest but at the same time it also shows useful functionality.
Got other cool use-cases which are short and to the point? Please blog about them, or drop me an email (or do both :)
I know that these kind of short examples are very useful to many people who are looking to adopt Zend Framework.
