This is a bit hacky and wasn't ever documented, I don't think...it was 
wedged in there for UT2003 on the Mac, and UT2004 on Linux.

In the "install" tag, add a "cdkey" attribute with the path where the CD 
key will be written:

     <!-- Mac version has this... -->
     cdkey="Unreal Tournament 2004.app/System/cdkey"

The installer will prompt for it. If there is a binary called "vcdk" in 
the same place as the setup binary, it will run that (with argv[1] set 
to the key the user entered) to validate the key. If the vcdk process 
returns zero, the key is invalid and the installer will prompt the user 
again. If it returns non-zero, it's valid and life goes on...the key is 
written to the file specified.
