Mail me a note when you have it. (later...) $ rm -rf /tmp/x The advantage of this is that you don't have to give any more access to the other fellow than you intended (your login directory can still be private, for example). Also, I think it's foolproof since you aren't going to remove it until you know that it has been received.
