From Apple’s Website: Back to My Mac puts any remote Leopard-based Mac you use within easy reach. MobileMe finds your Mac computers over the Internet and displays them in the Leopard Finder on the Mac you’re using. So you can connect from anywhere with just a click. Edit and save documents, open applications, and move folders. With Back to My Mac Screen Sharing, you can control your remote Mac as though you’re sitting in front of it.”
