TVEyes: "TVEyes, the real-time broadcast search provider, today announced Podscope®, the first engine to search within a Podcast. TVEyes’ Podscope, which makes every word searchable within a podcast, enables the audio indexing of podcast content, which is equally applicable to video blogs and personal videos. Podcasts are essentially downloadable radio programs distributed through RSS that can be put onto a digital media music player or iPod. Podscope will be generally available later this month."
