Sadly, iPad Peek is next to useless. It's just an IFRAME with iPad chrome graphics thrown around it. The only creative thing it does is a 75% scale in portrait mode, but that doesn't accurately reflect what the iPad really does.. and since it's just an IFRAME, you not only have to disable Flash yourself, but user agent detection and CSS detection schemes don't work, meaning most iPad optimized sites don't look anywhere near similar with it.
