Exciting! Egan is one of my favorite authors; he has an incredible imagination, and is one of few sci-fi authors who often puts an extensive list of citations in at the end of his books. No doubt the physics in this book are very carefully thought out. Looks like there are descriptions of the alternative spacetime he's using at the bottom of the page, so I'll have to give those a read!
