Search via images - Google future plan?

I read an article on searh engine called Otello, where the search command trigger by image instead of text.

This idea came from Vodafone. Showcased at CeBIT, the Otello search engine simply uses images as input; in other words, handset owners just snap a picture of anything -- a landmark, DVD case, unidentified flying object, etc. -- and Otello then "returns information relevant to the picture to the mobile phone." Reportedly, Vodafone is expected to conduct a trial with German paper Bild in which readers can "find out more about specially-marked articles by photographing them with their mobile's camera and sending the image to [the aforementioned paper]." Unfortunately, the carrier is being tight-lipped with its plans for Otello beyond the trial, but if this stuff functions as advertised, we can't see it remaining a secret for long.

I was thinking, how nice if Google provide such function in their search engine. Meaning you can simply snap a photo on some creature, say frog. You are not sure about the scientific name of that particular frog, Google will be able to match the picture with related write up about that frog... That's is something very useful..

Imagine... I upload a photo of some girl which you are pretty sure she is a celebrity but you do not know the name, into some Google page..

And search... The result page..

Nice isn't it?
