Do you have any insight?
I was just curious to see how you were planning to go about it. Actually, I haven't done a lot of research myself because my ultrabook and my BlackBerry both have Micro HDMI connectors and it's very easy to just plug in the cable and start a video playing, whichever device it happens to be on. We can supposedly do that on the iOS devices, also, with the appropriate "Digital AV Adapter," though we haven't bought or tried that. I just find it kind of comical that we have several devices capable of sending video wirelessly, yet each is locked to a different proprietary protocol to do it. My mother has a JVC TV that can receive video wirelessly using yet another protocol (I don't recall the name at the moment) which is incompatible with all three. For this to work for the consumer, he/she would have to settle on one wireless video standard and then use that standard as the primary deciding factor when purchasing all their products! Even choosing to buy all of one's products from the same manufacturer usually isn't possible except in the case of an unusual company like Samsung, which makes TVs, laptops, Android tablets, Android phones, and even Windows Phones.
Since I have HDMI ports on everything, I have assumed that if I really want to settle on one of those standards and start using it, they're all open to me so long as I can find compatible dongles for both the sending and receiving devices. It doesn't beat the convenience of having the functionality built into the handheld devices, but I figure that if we're watching something on TV, we won't be going far with those devices anyway, so what's one more thing to set on the table? (But iPhone 5s --> Lightning Digital AV Adapter --> HDMI adapter cable --> Miracast dongle -- that's a bit much!) I'm not seeing a lot of dongles available for sending of video, though; mostly just for receiving. That means I'd need a receiving dongle for each protocol and a separate port HDMI port on my TV (or an expensive switcher) to accommodate each of them, or a lot of device swapping which means I have to get up and plug something in anyway. Hardly worth it! I think I'll just wait this one out.
I expect that which standard wins will be determined by economics and its backing companies' strength in advertising to consumers and promoting to manufacturers. As it is, the situation is still not nearly as bad as it was in the early 80s where we'd take our movie on Betamax to a friend's house to watch, only to find out that they only have a LaserDisc machine. In that race, VHS won and gained ubiquity because of economics and a longer recording time, but certainly not because it was technically superior.
I'm aware that I'm getting a little off-topic here, so that's probably enough rambling!
