There is now an alternative to the client viewer, that's easy to use, even for someone who is not very computer savy. It's an online service called Real5D.
Real5D enables someone (like you or anyone) to do a tour through a "Virtual Reality" of your 3D design/model, interactively, online, in real time, in a very easy manner. It's very impressive, check it out at real5d.com. It also enables you do virtual meetings at the virtual model/site with others. I learned of Real5D when I met the CEO, Balazs Farago, of this new little, high-tech, startup company, based in San Francisco, at a friend's dinner party. He pulled out his laptop and gave me a demo: Real5D Introduction ("https://www.youtube.com/watch?v=SROgEPF5OxI"). The real5d.com website is interesting, lots of models to tour. Real5D uses multi-player, online, role-playing-game technology to turn your design/model into an online virtual reality. I sent Balazs a .3ds file of my latest project and his staff put it online for me, it's fantastic! You can tour a recent version of my latest design yourself at: Boswell-Boulder-Creek-house ("http://project.real5d.com/5d/projects/boulder_creek")
I've had virtual meetings with people, online at the virtual site I designed and modeled using CA-X6. We talked, I pointed to things using a virtual laser pointer. It's totally legit. For it to work, you have to download a free, thin client app. and the Mac version is still in beta. But, I think this service could be very useful to architects and designers who use Chief Architect, like to share their portfolio with prospective clients or to have virtual on-site meetings with clients within the design/model to talk about design changes and so on.
