@figuerres: They've got lots of tools for scanning sites for standards compliance. It seems like they could have an internal crawler. I read a blog post from somebody who worked on a particular site, and he mentioned that their web farm has thousands of separate web applications that get exposed to the outside world. I'm sure it's a very daunting task to standardize those. Although, you could probably pick 10-20 that got the most customer hits and focus on those.
