If you're on a POSIX-ish OS you can always open a temporary file read/write and then immediately unlink it to remove it from the filesystem. As long as you still have a file descriptor for it you can manipulate it any way you want. Pass it to Net::FTP, use seek to rewind back to the beginning, then read the contents. As soon as you close the handle the underlying storage on disk will go away for good.
