Feed Search at Yahoo?

Yeterday, Steve "I'm reviewing my logs" Rubel over at Micro Persuasion posted an item about noticing a crawler named "Yahoo-NewsCrawler Test" in his RSS logs. The Yahoo News "test" crawler (Yahoo also has a crawler named Yahoo Newscrawler) was also seen and reported in a WMW post about two weeks ago. Rubel's posts goes on to speculate that Yahoo might be adding an feed search option to their news search database and/or offer it as a standalong service. It's a good question but Yahoo! isn't offering any details about what, if anything, they're up to at this time. We asked Yahoo! for a comment and received back the following:
