ff-4 NNOS, looked more into it. much as some guru's would not except nano particles as nanotech, most people are not excepting nanosoftware now. regardless, with the cut backs in medical reinbursements, mri machine sales are way down then upgrades to older machines, i can only imagine will be up. so nano or not, this thing should rock! i also found out the PR campaign is suposed to be very aggressive, and this exxcode company they took on has lots of promise. good luck!
