Inconvenient WSSv3 RSS Feeds
Windows SharePoint Services v3 ships with a possibility to create RSS Feeds for every List. This feature is quite powerful as it allows you to create multiple RSS Feeds for one List based on Views. If you have worked with Lists at least a bit, you know that you can quite easily create a custom View using the standard SharePoint interface. Without any problems you will be able to define the filter and apply the sorting criteria.
