The CAVE thing sounds interesting.
I tried emailing the guy to include Blender in his suggestions for 3D apps. If you find a usable email address somewhere on his site let him know about blender.
I don’t think you’ll get an answer. That link you posted was last updated in 1999, so I guess it’s a dead project.
The vrml files are still downloadable. I did manage to email him at his present position in the hope of inspiring him to continue and go open source.
I contacted Mr. Sharov. He has switched jobs and is unable to maintain the site. If this is an interest to anyone in particular, he may be looking for someone to assist in updating his site. He was very interested in the blender info I sent him and appreciative.
