As CTAN mirrors Darmstadt, it will appear there two days after you've put it on ftp.cs.umb.edu. (The first night, it will be transferred to DA; the 2nd to CTAN.) I can trigger a `by-hand-update' if that's not quick enough. The faster the better. People can get it from ftp.cs.umb.edu if they need to get it earlier, I suppose. Thanks for the info.
