Seriously, while I agree with Karl and Pain in that scanning the directory structure shouldn't take that long, I have a ton of directories and sub directories and blah blah blah. It would be great to have some sort of "Super Cache" mode that allowed the creation of the XML file so that it was generated each time someone visited the site.
I ~think~ it would increase loading speed.
With that said, I also think that it should be an add-one product and not part of the core. Sell it for an additional 10$!
