How To Configure Joint Access To Files Stored In The Cloud Using The SkyDrive Desktop Folder

Hello. My brother and I both have laptops running Windows 7 64bit edition, and we both have the SkyDrive desktop app installed. Our goal is to access files stored in the cloud (as opposed to being stored on one of our computers), such that one of us can work on them at one time, and then the other can work on the same version later on in the day, such that we are always working on the latest version, without ever running the risk of our work being lost. Our goal is to do this not by accessing the files via the internet (i.e. in a browser window), but rather solely by clicking the little SkyDrive icon on the desktop to access the files. How can we set it up such that the files are visible in both of our SkyDrive desktop folders? A couple of FYI's: (1) We tried using the Share via e-mail feature, but all this does is provide a link to the files so that they can be opened in a browser. The shared files only appear in the SkyDrive desktop folder on one computer, not on the other. (2) We used to use a program called JungleDisk to achieve this, using its Shared Drive feature, such that the folder was visible on both of our laptops (just by clicking a shortcut) without having to use an internet browser. That is what we trying to achieve with SkyDrive. Is it possible, and if not, if anyone knows of a program or programs that enable one to do this, please let me know! Many thanks in advance for your time and counsel.
