My family has two houses. Can we stream in both locations on the same account?

We have two houses about an hour apart.  I'm spending most (but not all) of my time in one house as I fix it up into a vacation home.

She and the kid are still (mostly) living in our other house.

We have Roku devices on all of our TVs.  The Xfinity app will only work at our old house/old internet.  At the new house it says it can only be used on our home network.  As a result, I'm looking to switch off Xfinity.

For DirecTV on ROKU, can the 3 of us stream different shows, if I am in one house and she and the kid are in the other?

I'm looking for the official "terms of service" answer.

I know it would PROBABLY work, but I also know they could track IP Addresses and lock it down to one if they wanted to.

I also figure I could do it on the computer instead of Roku but I already can do that with Xfinity and I don't like it.

Thanks.
