Streamlining (and Slipstreaming) your Unattended WinXP Install onto CDR or DVD

Required for this endeavour:

Completion of Part I
A CDRW or DVD+/-R(W) drive (CDRW is fine, but a DVD burner is outstanding for this project)
At least 1GB of free space on your hard drive
Time. This project will take some time. I'll explain in a bit...
Windows XP Pro or Home CD with key
3rd Party CDR(W)/DVD burning application, such as Nero or Roxio

Highly recommended for this, but not required:

A working knowledge of how batch files and regedit files works is very helpful
A broadband connection (you'll be downloading XP SP1a - not a small file)
VMWare or Virtual PC, for testing your work, OR;
A spare hard drive (again, for testing)
