you need to be conscious of any outlets that are controlled by a wall
switch. Often when this is done, half the outlet remains live, and half is
controlled by the switch. The wiring scheme looks the same as any other
daisy-chained outlet, except there is a small brass tab on the "hot" side of
the outlet, that must be cut first. If it's not cut, the switch will have no
affect on the outlets it should control. Also, be aware that there may be
other wires in the outlet box, that are not attached to the outlet. These
may be from another circuit and may be alive, leave them alone

I don't suppose somebody wants to try explain Edison circuits...
