if the router autodetects it wouldnt make a difference as to what kind of cable was used. i believe he said crossover because it would be needed for an access point designed to be wired directly to a switch from a router with a straight-through cable.
it could also be done with a wireless router sitting there, only plugged into power and any comps you cn hook up via wired. then pu the wireless adapters in the comps and you can share files over the wireless network while still using the other network for internet.
but for large transfers i reccoment doing it over cat5 instead of wireless, on 802.11b i get about 6 mb/sec when im lucky, usually around 4, while wired betwen the same comps i get around 65 to 70 mb/sec. ive never tried to stream a dvd quality movie over the wireless, so im not sure how that would go. if it was under 3 or 4 mbps bitrate it sems like it would work, aslong as you dont have interferance problems. at my work i have a problem with my laptop gettin disconnected every time the cordless phone rings. kindof annoying but im the only one who uses wireless.
