multi-touch of resistive screens isn't related in any way to stylus. It's just that capacitive screens - the type that is pushed on us from almost every new device - is often multi-touch capable, yet, not usable with stylus.

On the other hand, multi-touch capabilities in resistive screens isn't anything new, yet, it was never widely implemented. Kinda pity, as resistive screens beat capacitive crap in every single way.
