Windows/Mac/Linux: If you're interested in the idea of cloud computing and remote access to your files but a bit paranoid about putting your data on some third party server, Tonido is a great compromise. Tonido brings cloud computing home by using your computer as the storage server and host for the applications. Once you've installed Tonido, the only function the Tonido servers themselves perform is keeping track of your IP to make remote logins easier for you. Tonido has a juke box for remote media streaming, a photo organizer, a blog-like personal journal that has support for web clippings and Twitter integration, easy file sharing with Webshare folder management, and a workspace with calendar, notes, and task lists.
