Lifetime subscription is for the life of the unit, not the owner.
If you sell your unit, the lifetime subscription you paid for goes with the unit. The new owner would have the lifetime sub.
This is one of the more misunderstood things about the TiVo service. I'm not sure why. Seems pretty clear to me. Compare the prices on ebay. Tivo boxen with lifetime sub always goes for more money. If yours is broken and has a lifetime sub, someone will buy it just for the subscription in hopes it can be brought back to life.... or they'll just steal service.
