PyCeed is a simple web-based feeds aggregator. It supports feeds union, pruning, sorting, and filtering. It contains a web server that serves simple config pages and feeds in both Atom and RSS formats.

IOW: a very trimmed-down Yahoo! pipes (which is about to close in a few months): no fancy operators, no pretty graphical configuration.
