If there be any white papers or in depth analysis on the technology itself I haven't heard anything. I believe the management of Sphere3d is holding their cards pretty close to their chest and not releasing a whole lot. I know they have filed quite a few patents but I'm sure those would be way too advanced for a layman such as myself to even begin to understand.
I just wanted to get in on the ground floor before the masses. If it works the way they say it does I'll just have to believe them.
