Using a Tivo without a CableCard.

Hello all. I have a question that I hope someone here can answer for me. I currently have a Tivo Premire XL with Lifetime Service. I want to purchase a Roamio Pro with Lifetime Service. Now here is where my question lies. I want to take the cable card from the Premiere and pop in into the Roamio. I then want the Roamio to be able to access the Premiere's hard drives and/or tuners and allow the Roamio to be able to record on the Premiere. Basically I want to use one cablecard (in the Roamio) and utilize the hard drives and/or tuners of the premiere (no cablecard) over my internal network. Is this possible.



Thanks
