The hair room...well, the only real issue there IMO is the collision detection. Some complain about the hair looking like wire, but that's just the default settings and it can be overcome. The hardest part for me is styling the hair - I'm an engineer, not a hairdresser, and it definitely shows through :) RAM usage and render time - that's a problem common to all strand-based approaches, but if you look at current motion picture CG (Monsters Inc, Stuart Little 2, Matrix), strand-based hair is coming. About the face room - I'm only waiting for some of your fellow Frankensteins to put Don's head on Mike (we have seen all kinds of head transplantations, why not this one?). Once you do that, you have your long-requested face room-ready millenium figure.
