Adding Ghost boot.wim to Windows deployment Server (WDS)

Hello, is there any new information on using Ghost with  Windows deployment Server - WDS?

I have extracted a boot.wim file from the following process:

1. Ghost Boot wizard
2. Windows PE
3. Create Ghost Boot disk
4. Save as ISO
5. Extract boot.wim 

I then imported to the WDS server

Unlike Windows boot images in WDS you cant right click the boot image from ghost and 'Add driver packages' (it is greyed out), so the Q:
 

1. How would you add network drivers to the Ghost boot.wim
2. Am I right thinking these need to be Vista network drivers as .inf files?
3. Does Symantec have any plans to get this (right click 'Add driver packages' menu) to work?
4. Is there a new Ghost Boot Wizard that will creatre a newer Ghost ISO and hence a newer boot.wim?

Why is this so difficult...with 'Ghost with RIS' I set it up, it worked, I never had to add drivers....
