At Campus Party Brasil 5, I was talking with Jessie and Kul about features for Mobile.
One think that Jessie suggest, is a plugin for browser, like Firefox Mobile, that you highlight a word and then click on search and it redirect to Wikipedia mobile, and if it's not installed yet, redirect to Market.
I'm working now on it to make a configuration pop-up to selection the search language and how would like the search appears: (Pop-up, new window or new tab).
