Interesting, I thought the Yuuzhan Vong hated ALL force users. My theory about the Vong's Force "Void" is that the "Force" is a localized energy field / genetic trait in the Star Wars galaxy. All creatures that evolved outside the Star Wars galaxy don't have that trait and therefore are an alien object to the Force.
EDIT: But then, I think the NJO is just a bunch of non-canon Star Wars hype.
The books totally jumped the shark in the Jedi Academy Trilogy.
