The sad thing is that somebody out there (probably Autodesk) is busy frantically adding leap motion support to their product as we speak...

Part of the reason I haven't been sold on a space mouse is that ergonomically it doesn't seem to make that much sense. Perhaps it's a learning curve thing, or the awesome ergonomics of the Thinkpad "nipple mouse" placement, but I work insanely fast in MoI with great comfort.

The same could be said for Rhino with the difference being that I find the keyboard controls in MoI to be much more intuitive.
