Lars,

Yes, that's right; those are the documents that would need to be signed for 
logo testing.

I'm not sure whether there is a subscription fee for maintaining the account, 
but there is a fee for every driver submitted for logo signing. Logo testing 
will also require some hardware resource and engineering time - alas the 
testing does require a bit of hand-holding. So I guess the question is whether 
having a logo tested and signed set of drivers for the community?
The other simpler option would be for the Xen Project to just acquire an EV 
code signing cert and a dev centre account and then use the Microsoft portal to 
release-sign drivers.
