Yup! We use archive.org all the time, because we often find scrapers who took our content 2 or 3 years ago, and we have to find the version of our site from the time they took our content and send the correct screen shot. Or sometimes you find a domain name registered say in 2007, and you know he stole your content to make his site, so you have to get a 2007 snapshot from archive.org, and it's easy to show the web host that the offending site has no archive.org content, which proves your content was up first.
With some of these web hosts, if you don't send them a 100% match, they might balk at it, or say something stupid like, "we don't see a cut and paste, we something similar but no cut and paste."
