Thanks! - Actually, there aren't that many sci-fi references, just a few minor ones... well - with the exception of H. Beam Piper from whom I've borrowed liberally (as his works are in the public domain). Plus some authors, of course, and a few "generic" names. I'll put Golter in for the next update though. I must admit that I never read anything by Ian Banks, though I love his variation on the Ringworld concept (the Banks Orbitals) who are definitely part of my universes.
