Interesting question - you could take automated screenshots, save them in a lawyer-friendly format (e.g. PDF) and then add a certifying signature with a secure timestamp (perhaps adding the raw pages and images from the site as attachments to the PDF as well).
If the target market was lawyers you could probably charge a chunk-o-money for it as well...
NB I have no idea whether such a service already exists.
