I currently have a lifetimed single tuner S2. I want to buy another lifetimed S3(I already have 1). I don't have anywhere else to use the S2(the S3 would be its replacement) and I don't want to sell it in case I do need it one day. I want to let my parents use it. they live in the same city as me(just around the corner actually). is there a way i can let them use it without actually transferring it over to them? they don't have any type of network so it would have to dial out in case this matters. I currently use it with the Tivo wireless adapter here. what are my options here, if any?
