LeafRSS is designed to be a low-maintenance, learning RSS aggregator, with the ability to publish the aggregated results either in a standalone website, an rss feed for news readers, or as an embedded template within an existing site.
Jebi allows users to record AM or FM radio, TV or other audio content to MP3 and automatically publish as podcast channels via RSS. The result is a Tivo-like capability for radio (Rivo?). Tuner cards are supported.
