Deep Web Technologies is sponsoring another contest in which you "Tell us about the most impressive federated search application you've ever seen, or about one you've dreamed up. How innovative can federated search be? What unique problems can it solve?" What's kind of neat about this one is that it's not just an essay contest - they're accepting any form of submission; video, audio, written, etc. The winner will receive $1,000 and a trip to Computers in Libraries 2010. Check all the details at the Federated Search Blog, and keep in mind that entries must be received by Dec 15, 2009.
