I'd love to see ideas from races in Jack L Chalker's Well of Souls Saga (the original, not the sequel trilogy, which was IMHO trash), particularly from the Northern Hemisphere of the Well World-AKA the really unusual and typically non-carbon based races. Bozog, Wohafa, Uchjin, and Yugash? Yes, please! Which is not to say that there aren't some very interesting Southern Hemisphere races as well. :)
