So I headed over to real.com and downloaded their free player -- my word, but I have never seen such a long EULA! And some of it looked pretty ominous. So I decided not to install it after all. Rats.
But today I got around to installing Netscape Communicator 4.8, which I wanted to keep around to see how things look in an older browser -- and it comes with RealPlayer Basic, an older version (8, I think)! So I'm a happy camper now.
