Christopher, You have to remember who you are talking to; Wol is ignorant and stupid. A car is a physical artifact just as the physical representation of a datum is a physical artifact. Physical independence is the equivalent to having a door from the hallway to the garage, a door from the kitchen to the garage, a door from the back yard to the garage, and car access to the driveway--and an identical car parked in the back alley just for convenience. Wol's analogies are dumb because they reflect his intelligence. ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
