Speaking as the chair of the Security Subcommittee of the SGIP's Smart Grid Architecture Committee, my inclination would be to have the light controller be able to authenticate and authorize messages instructing it to modify the state of its light bulb, and determine whether they are from a switch that is authorized to initiate such messages. Absent that, I submit that the 21st century equivalent to TP'ing the house of the cute person-of-opposite-gender down the street might be to have their lights making statements using Morse Code.
