I am contemplating setting up an FTP server for a magazine client of mine. I do the production work for layout/editorial, etc. He handles the ad design. We are going to need a remote server so I can get his .psd, .qxd files so I can create the signature layouts. Was going to invest in a MacMini or cheap PC with Ubuntu to make it my FTP server. Already got an account set up with DynDNS. On the flip side, I looked into Amazon S3's services. Their cost per GB per month is dirt cheap, making it a possible alternative vs. me investing in the hardware/time to set it up. Has anyone used S3 as a pseudo FTP server? Any feedback would be appreciated.
