Frontier

If you download and install all the Frontier files from this site, you can easily create your own News Aggregator? It's all there: when you run Frontier, it will create its own aggregatorData.root with all the stuff you need in it. Also, the xml.aggregator verbs are still available, so with a bit of scripting you can make it scan for new stories hourly. The only thing missing is a displayer, but for a Frontier developer, or in fact anyone with a little programming sense, it's a piece of cake to write one.
