I have a feature request... to dump a single text file, gzipped, of ALL of the urls that go into the various sitemaps.

Basically... when we're in the loop to create the various sitemaps, to additionally write a text file, with just one full URL per line.

This is because this would also be good for Yahoo and other spiders. Yahoo specifically asks for such a thing on their submit page:
http://submit.search.yahoo.com/free/request

You can also provide the location of a text file containing a list of URLs, one URL per line, say urllist.txt. We also recognize compressed versions of the file, say urllist.gz.

And to me... it seems that the loop to create the Google Sitemap, is the perfect low overhead place to also dump the Archive URL's into a text file for Yahoo and other spiders to feed from.
