Virtual Reality/CAVE Software?

WorthlessManatee asks: "I work for a company that is in the beginning stages of constructing our own CAVE and I would like some advice on a few topics. Which hardware vendors should I go through? I know of Fakespace, but are there other vendors I should be looking at? What software solution works best for a CAVE? So far I know of: VR Juggler, DIVERSE, and CAVELib? What are the pros and cons of each of them? Answers to these questions and any other hints or experiences you would care to share would be most appreciated. Thank you very much."
