Microsoft's FolderShare -- to securely keep files synchronized between your computers, share files with friends or colleagues, and remotely download your files from any web browser - transfer up to 10,000 files up to 2GB in size each (this is sort of magic)

FolderShareTM is a service that allows you to securely keep files synchronized between your devices, share files with friends or colleagues, and remotely download your files from any web browser.  Need to send or receive files that are very large - up to 2GB?  Use the FolderShare, file synchronization service (acquired by Microsoft in November 2005) that is now part of the Windows Live family. The software runs on both Windows and Mac OS X.  After installed:  If you haven't used FolderShare yet, on the Welcome screen, click "I don't have a FolderShare account."  On the New Account Information page, choose a nickname and password and type in your e-mail address. Check the box certifying that you're over 13.   The software will connect to the FolderShare server and create your account.  On the "choose a computer name" page, the default is your computer's name on the network.  Accept this and click Finish.  You will see a flashing icon in the system tray.  Click on a FolderShare library if you've been invited to share one, or click My FolderShare to go to the web site and set up a folder to share, synchronize your folders, share your folders with friends on the Internet, or access your files.  FolderShare operates like a private Peer-2-Peer program. Those you invite can share items in the folders you designate to share, but can't access anything else on your computer.  Your information is not stored anywhere on the Internet, and you computer must be on for others to access the shared files.  Get FolderShare at http://www.foldershare.com/.
