PackRat. Take your Backpack offline

Packrat is a desktop client for 37signals' Backpack web application. Packrat lets you use your Backpack data when you're offline. Before you hit the road for the first time with Packrat, just use the Sync command to sync with Backpack and your data is duplicated on your Mac. View and edit your data offline or online. When you're online, Packrat will automatically inform Backpack of your changes and Backpack will be up to date.

the killer syncing and offline Backpack client that does even more than Backpack itself
