I need an FTP client that will upload one file to multiple servers. In other words: you save the login data of multiple servers, then give the command to upload the file and the FTP client will connect to all hosts in the list and upload the file. Here's the kicker: I'd even be willing to pay for this piece of software.
many ftp programs have have a macro function that will do this. You initially setup the macro and tell it what you want done, then just run it. Cute FTP has it and I'm almost positive WSFTP has it as well.
