Choosing a web based location like iDisk is possible using soft links. This shouldn't be done while Things is running.
These steps should be repeated for each Mac you wish to keep in sync. If you forget to mount your iDisk before opening Things, you will receive an error: "Your Things library could not be opened". Simply choose the "Quit" option, mount your idisk, and reopen Things.
