I have been using ExpanDrive mostly to access a remote server and absolutely love it. With the new version 2 you now have access to Amazon S3 accounts. I now use it to access my S3 account and absolutely love the convenience. I rarely have to open an FTP application anymore. Once you log into a remote server via ExpanDrive you have full access to that server just as it where an external HD attatched to your computer. You can just drag & drop files from the Finder to the server sitting on your desktop and in Finder window sidebar. Also, all the servers you are connected to show up in the standard Mac Open/Save dialog windows from within any application.

ExpanDrive 2 is a great application that just got a whole lot better. I love it!
