Another cable cutting strategy. Parents rent an additional cable box for $6/mo. and hook up a sling box. Kids in college or in their cableTV-less homes watch the sling. For $6/mo they've got full cable service. PQ isn't perfect, but it's on par with other internet TV.

Another good option is the have the parents get an extra DirecTV receiver ($5/mth mirror fee) Dish Network insist on all rcvr's being connected to a phone line but directv doesn't care. about 5 plus years back when people started adding rcvrs to their accounts for their RV and cabin up north and so on the phone line requirment was dropped and just requested if possible. Also if you use a rcvr in a second location with a phone line on a dif. telephone number they don't really look at that, you'd think they would but its no problem.
