I just stumbled across a blog post from Claus Valca  refering to VistaPE, as I could judge this is more or less a replacement for BartPE which has been dead in the water since 2006.

VistaPE should allow you to create a bootable CD/DVD with the Vista kernal (much as BartPE did with the XP kernal), this is useful as a recovery tool/image tool/repair tool/virus cleanup tool etc.  I have previously created antivirus cleanup cd’s using BartPE, but maybe VistaPE could offer better compatibility with the later hardware models.

I will add this to my “I have to look into this list” (which sadly has become quite long)..
