Have you thought about integrating these similar features into Chrome via a plugin?

Would be fairly good to be able to search Wikipedia by typing w: in the URL bar.

You can already do this in Chrome. For example, I hit ' to search Wikipedia and hit ; to I'm Feeling Lucky Google.

Preferences -> Basics -> Manage (Next to Default Search)

On top of that, most pages with a functioning search get recognized by Chrome, so for example if I type "e" and hit tab, Chrome lets me search "en.wikipedia.org".
