There seems to be the understanding here that you need your Wifi network in order to stream music to the BeoLit 12.
That is only the case if you want to stream your iTunes music from your PC/Mac to the BeoLit.
You can however wirelessly stream directly from your iPhone/iPad to the Beolit without using your home wifi..
I watched B&O's wifi setup "training" video on YouTube ... it is unclear how you would activate (there is a registration process) the BeoLit 12 and have it accessabile away from your home network ... can you outline how you believe it will work ?
