The trouble with the level of VR presented in SAO really isn't creating the world. The true challenge lies with the neural interface. Being able to properly intercept outgoing muscle control signals AND generate the correct input signals for all 5 senses is the biggest barrier, and will thus be the biggest breakthrough, for a system like NerveGear/Amusphere. Right now, all we've got is video screens and game controlers or motion tracking. I believe the early chapters of Volume 1 mention the problems with that.
