I was thinking a little deeper than that.

A lot of software (eg firefox, opera, various graphics etc) have "local" ini and config files. Supplant those and you could have control through, say, browsers as to where the browser is directed (eg startup page etc). Not sure that could actually happen but it's a possible entry point.
