About a year ago I posted about sfdcFuse, a command line utility that exposes the Document repository in Salesforce.com as a mountable volume using MacFUSE. Unfortunately this version doesn't work on Leopard, so I've been working on a Leopard version, and at the same time, getting rid of the command line interface and putting a regular cocoa front end on it. The result is SFFS (the SalesForce File System). Much like the earlier version, this exposes a read-only copy of your document repository as a mounted volume on your Mac. You get my standard UI for login, complete with keychain support, and auto-updates via Sparkle. Its available under the open source BSD license, everything is over on the Google code project.
