From Kendra Scalia's Electronic Visit Verificaion (EVV) is Here:  What you need to know and how to get involved:

"Whatever may come to pass, the disability community is clear.  We refuse to be treated as patients in our own homes. My house is not an outpatient hospital or nursing homer.  There is never a reason for the government or their vendor to have access to the private dealings of my life solely to prove I am disabled and in need of assistance."
