Okay, I've been testing this out for a couple of hours on some expired domains I fond, and I can confirm this a must-have piece of software to add to your SEO arsenal. You can choose specific snapshots of the site to recover by entering the URL of the snapshot (so you can capture the site as it was in June 2005, August 2007, whatever works best for you), it seems to grab all pages, files and data that were archived at that time.
I loaded the HTML outputted in Firefox and was super impressed to see a literally perfect replica of the site, ALL archived images in tact, ALL archived links working, NO Archive.org code in the source code (I CTRL+F'd for "archive" and "wayback"). Looks exactly the same as it does on the Archive.org website.
Restoring sites from the Wayback Machine used to literally take me all day. Now it's done in less than a second. In fact, this tool has made restoring domains easier than creating expired Tumblrs.
Think you'll be spending time changing the image and internal links from "My Documents/..." to "yourdomain.com/"? Nope. You can enter your own link prefix and it alters all of these for you, so when the site goes on your server it will all be perfect. No opening and re-opening HTML because JPGs are pointing to the wrong place.
So yeah, so far I'm liking this tool a lot.
My suggestion to make the tool even more awesome:
The option to restore the site to a server via FTP. You've eliminated lots of steps of domain restoration, and this would eliminate one more.
