I agree... interesting idea. Here's something to think about though: Unless you have a high OPTICAL zoom (vs. digital) it will be a poor quality image even if you patch it into a flatscreen as mentioned earlier. The digital zoom takes the maximum optical zoomed image and just blows it up. So really it just turns into a very poor pixelated image.
Not a very good explanation but this may clarify what i'm saying:
