I poked through the Slingbox website and US purchased units are 120V only. Therefore it would be easier for all if the Swiss partner purchased the Slingbox locally.
Supposedly, there is a ROKU App that plays Slingbox. Does anyone have experience with this? My customer is an elderly woman and the user interface should be straight forward. Of course, since she is a Mac person she could play Slingbox through her Mac, but this complicates things physically because I think a TV should be used as the display. This is a new installation, there has been a single phone conversation with her, the walls are open, but I don't yet know what kind of "deck" I'm playing with.
She (a customer from 25 years ago) has a friend (also our customer) with Sonos and this seemed very attractive to her. I mentioned that Sonos can play Internet Radio from around the world and she brought up the idea of Swiss TV. I have not yet mentioned Slingbox to her.
Does anyone know if the Swiss ISP's offer "all you can eat" deals or is the billing strictly use based?
