thanks for the link

its an academic project so i am not sure if we'll ever see it on the market. not soon, i guess.
academic paper: http://tei-conf.org/10/uploads/Program/p241.pdf
in there they mention a similar mouse: http://www.orbitamouse.com/ // 80$ (in fact any mouse with a scroll wheel would work)
the paper mentions u can have more than 200 mice: modular controller, there we go!

touch-screen isnt it the only way to make use of multipointing OS as it seems
