I need to do reliable streaming of video from a Windows Phone 8 app to a Windows Store app. Currently I am doing this via sockets over Wi-Fi with a wireless router in the middle like this SO solution suggests:
How to stream video from PC to Windows Phone 8 mobile phone through internet
I can no longer use a solution like this because the production environment for the apps will not have a wireless router available so the Windows Phone device will need to talk directly to the Windows Store app running on a laptop or tablet. I've heard of something called Wi-Fi direct but I am having trouble finding the information I need in this context. Here are my questions:
Can I use Wi-Fi direct? If so, is there a decent sample or document that covers my app context of streaming video from a Windows Phone 8 app to a Windows Store app?
If I can't, is Bluetooth reliable enough to stream video smoothly? If so, any examples that show how to do this would be appreciated.
If both are viable solutions, which is the better one using smooth frame rate and reliability as a the criteria for judging?
If I turn the tablet/PC or Windows Phone into a hotspot, would that allow me to establish socket connections from my apps?
Hotspot questions extended. Will the hotspot solution, either phone or tablet/laptop, still work if the device providing the hotspot does not currently have access to a network? For example, if the phone can't access a 3G/4G network, can it still act as a hotspot for the tablet/laptop? I know there won't be Internet/Web access, but can the devices still talk to each other?
I found this SO post on Wi-Fi direct but it covers Android:
I found this SO post on Bluetooth streaming but it covers Android and iOS:

Would turning my laptop/tablet running the Windows Store app into a hot-spot work for my context?:
