If you haven't noticed yet Bigelow aerospace has updated their site
The info on his inflatable modules is still almost non existant, and quite vague. But there is some interesting info there, On the upcoming Genesis module(lauch June 16) there will be 1,000 photocards and small personal objects contributed by Bigelow employes, that will freefloat around Genesis after it is inflated. Six onboard, and seven external cameras will stream video to Bigelow's new website. On the next Genesis launch, you can buy space for your photo or personal item.
It would make an interesting add-on for orbiter, especially if you could simulate the stuff floating around inside. just have to wait and see :)
