Is it possible to do some processing of posts and comments to automagically add links to the wiki for technical terms(possibly any word or phrase with it's own page?).

I'm thinking of the annoying ad-word javascript that some sites do. I've always thought it would be useful to do that linking without the author needing to(but possibly being able to override), but most wikis require you to make links manually, because of ambiguity. Given the specialist nature of this wiki, shouldn't that be less of a problem?
