You are right though maybe there is another way to do it... though www.feedbooks.com
The link http://www.feedbooks.com/feed/25.epub
will give you the RSS feed for Engadget and I am pretty sure the link remains the same day after day with only the content changing.
There is also a part where you can make your own feeds and maybe the download links will remain the same..
