Comcast has had free wifi hot-spots for a few years now, but in places like parks, not anyone's home. I would want it in writing, signed by a comcast corporate officer, that there is a separate IP address assigned to the free wifi hot-spot I'm providing so when somebody parks in front of my house and downloads a few gigs of kiddie porn I don't wind up on the sex offender registry. Unless comcast isn't telling the truth here, providing a document like that shouldn't be a problem,should it?
