Good federal legislation?

There's a bill that's expected to signed into law soon to criminalize peeping tom uses of picture phones. My first reaction was to agree with Radley that this was needless federalization of a crime, but it didn't take much reading of the article to see he's having a bit of a kneejerk libertarian reaction. Assuming the article is accurate and that the bill is written with the proper narrowness, it would only apply on federal property, so we are talking about a legitimate area of federal legislation. See, I do sometimes favor adding new laws, at least with those caveats mentioned.
