TBF I face much more challenges saving data _from_ the WaybackMachine using the CDX API than most of the sites I've scraped:
Most tools for offline archiving simply don't work, and although I'm *really* slow with my requests I get throttled all the time :P
Oh, and I almost forgot that it's surprisingly hard to translate IA URL's to local file paths, esp. since the URL's retrieved from the API aren't properly encoded (https://web.archive.org/.../http://example.com/...)
