Here is a direct link to the argument. (RealPlayer required.) The archived version is not yet available. Sometimes it takes some days. I hope they will be quick about getting it up in this case.
[Update 5:15pm: The link above is live, and has been since 3:00 p.m., as Marcia Oddi at the Indiana Law Blog has written in a comment below. I guess I couldn't get on at 4:00 p.m., not because the archive wasn't there, but because I was in line behind the rest of the world.]
