Can multiple boxes being used on one subscription watch TV from different locations at the same time?

The 5 boxes sharing one account can be anywhere in Switzerland and watch TV independently of each other at the same time. They do not have to be using the same Internet provider. All boxes share the same recordings, i.e. you can record a show from the box in your living room and then watch it on another box e.g. in your weekend house in the Tessin.
