I'm looking to work out a long term upgrade plan, that benefits all in this scenario. My sisters and my parents TiVos are all hand me downs from me. So, if I want to do switching, they're all agreeable. My House 1 S2 Dual-Tuner w/ 3 year commitment 1 S2 Non-Dual-Tuner w/ lifetime Sister's House 1 S2 Non-Dual-Tuner w/ 3 year commitment 1 S1 w/ lifetime Parent's Vacation Home 1 S1 w/ lifetime I don't think either of the S1s are grandfathered, but I'm not sure about the one at the Vacation home. Should TiVo offer lifetime transfers (please...) I would buy new S3/HD boxes for my home transfer service off the 2 S1s, keep my Dual Tuner S2, give my S2/lifetime to my sister and pay for month-to-month service on my parents S1, since they're at their vacation home like, 2-3 months a year. Would something like that work? I mean, theoretically, of course.
