Wrote a quick little tool for mounting Box.net accounts to the Finder of Mac OS X. This allows you to interact with the Box.net service as you would a MobileMe account or a file server. The tool connects to Box.net over WebDAV and so you will need to provide you username and password (which can be saved into your Keychain) for your Box.net account with each login. However, you can put the tool into your startup items, login items, etc. Future releases might include the ability to store your credentials so you don’t have to provide them any more or the ability to synchronize your files from your Box.net account, but this fills my need for now and so I hope you will find it useful as well.
BoxMounter can be found on the Apps page of this site. Hope you enjoy!
