I would think, and of course could be wrong, it would be as legal as Google scraping all of the web sites that they do in order to create their search engine in the first place. In particular, Google provides cached versions of web pages. That's pretty hardcore scraping.

I put "legal" in quotes because I assume it's not criminal. It would, though, likely result in some pretty quick civil action.
