This reminds me of Angelfire's ftp setup. You got free hosting, but to upload, you had to upload to their open ftp server and use the control panel to copy files into your webspace. The files on the FTP server had an expiration of so many hours, but was otherwise unrestricted. You could upload files larger than what you could use in your free space. It became rather interesting to just browse what people were uploading to the FTP server. I eventually found some people were just using it to transfer files, and some were using it like a message board, dropping .txt notes to each other. These notes were usually just things to indicate some larger file that was being uploaded.
