Like some of the others mentioned, I'll use the ellipsis to indicate the thought just kind of trails off. But on top of that, I'll use it in the middle of a sentence to give the feeling of a change in direction or thought. For example, in a previous game I had a character where the common language wasn't her first. So often she would get lost in the middle of a sentence, searching for a word, and the ellipsis came in handy in portraying that. Something like, "Your idea is... oh, how do you say it? ...ah yes, it is crazy." Admittedly that may not be the 'proper' usage, but it seems to help get that feeling across.
As for responding to an ellipsis, I'm of the feeling that, unless someone has given me an indication that they're continuing a long thought, once something is out there I can respond to it. Just like in spoken conversations, people sometimes interject whenever an opportunity appears, even if the original speaker doesn't feel like they are done yet.
