Hmm, let me rephrase. I have a PC with MAC address x1 that needs to have a standard Windows 7 install without user interaction. During the installation the 'procedure' should match MAC address x1 to PC-name y1 and OEM key z1 which it will find in a list (database, file, ...) and use these variables when installing Windows 7. Nothing fancy. I think this can be achieved by using a database in MDT, right? Auto-activation seems cool but is not required. Let's start easy :-).
