The files offered are for running a dedicated server using only an executable and some data files, apparently without having to do the whole 3-CD installation. A free CD-KEY is available by emailing Epic.

Files can be found here. At 247MB this is quite a download, but if you have a dialup connection you can obtain a CD containing the files as well.

I haven't had a chance to try this installation but will post a review when I have.
