I came across this wonderful website a.k.a. tveyes.com
They have very interesting concept. It employs special technology so when you order a search with particular search term, the underlying search engine will scourch the web and find all video clips which has that particular search term is spoken in the clip. It is very interesting and I personally think this technology has tremendous dimension just imagine you can record all your conversation and then one fine day you search your audio clips with particular "phrase"....wow.
I love this technology and I think more developer should focus on underlying technology to find more uses.
