but live preview

Answer 1

You could do the following:

1. Create (or find) a service that renders URLs as preview images
2. Load that image on mouse over and show it
3. If you are obsessive about being live, then use a Timer plug-in for jQuery to reload the image after some time

Of course this isn't actually live.

What would be more sensible is that you could generate preview images for certain URLs e.g. every day or every week and use them. I image that you don't want to do this manually and you don't want to show the users of your service a preview that looks completely different than what the site currently looks like.
