Please see
bug 40067, filed by me.
I have tried to connect to the Briefcase using Windows 7, but have been unable to.
Windows 7 (and previous versions) supposedly has the option of connecting to a webdav share, much like it connects to a network folder, to use a SMB/CIFS share just as it uses a local drive.
If anyone has had success with this with Windows 7, please show me how you've done it, I would be very grateful.
I would also like to ask people to try this out, and if your setup fails too, please add your weight to the bug to increase its awareness.
Being able to simply, transparently replace a SMB/CIFS server with the Briefcase service would be great.
