I remember doing this, transferred a few large (at the time) files from one server to another. There were definitely some clients which had this feature, but I cannot remember which one I was using specifically. If I remember correctly, I did this because the servers in question were some "free" webhosting things where you'd only get ftp access (along with http, of course), but no shell. I also remember talking to some people back in the day who regularly did that supposedly. Members of some minor warez group who uploaded new releases to one server and then used FTP to directly transfer files from one server to another to create mirrors. Then retransfer from the two servers that now had it to even more servers for some exponential growth.
