For those of you who aren't familiar with Egan's work, I can't recommend it enough. All good scifi indulges in world-building, but Egan's is the most scientifically well-thought-out I've seen, as well as containing some very plausible depictions of post-humanity. Many of his works are available in their entirety on his (delightfully 90's) website, http://www.gregegan.net http://www.gregegan.net.
