The German productivity blog Die Kritiker mentions an interesting use of DEVONthink: Backups of the online productivity and collaboration suite 37signals’ Backpack:
You simply create a link for your 37signals’ Backpack account in DEVONthink. Selecting it loads Backpack inside DEVONthink with full access to all your data. Now, select the page you want to backup, Control-click it’s background, and capture it as a webarchive. Done.

It may just be a mistranslation, but the online productivity and collaboration suite they’re referring to is 37signals’ Backpack (not “BackPackIt”).
Lyle: True. Corrected. Thank you!
The web address for Backpack accounts is http://username.backpackit.com
