Killer feature for Mac OS X?

What if when I typed into the search box in Safari (Mac OS X's web browser) the text is interpreted by Siri? I could type "What's the weather tomorrow" and it would display a forecast for tomorrow, or type "text my wife that I love her" and it would initiate a text message to my wife. Wouldn 't that be cool?

I just typed into the search box "Is Kashi a company?" because I was in a Siri kind of mood, and of course I didn't get a good answer. But maybe Siri on my iPhone would have known. (Update: I just tried it, and it didn't but still, I think it's a cool idea!)
