Networking Tivo without subscription?

Hey all, I have two tivo's already fullly networked and love the ability of watching what I want where I want.
Now I have been given a Tivo from a friend, is there anyway to network it without paying for a subscription? I wont be recording anything on it but just want the ability to watch recorded shows from my exitsting Tivo's on the TV on my screen porch.

Thoughts???

Thanks
