The BM TV Studio is a hardware switcher that comes with its own software. You'll have to use the BM TV Studio Switcher software to switch between one of the 6 inputs on the BM TV Studio, vMix will only see things as one input in the configuration vision you've shared. Your vision, similar to mine when I first started out, would be better suited to getting BM PCIe cards for the computer you run vMix on. The BM Quad and Duo cards are the best options to add inputs for vMix to use for switching, these cards both use SDI in/out but only one direction per channel. There are many other cards available, look and research all the ones available under supported hardware tab on this Website. You might also want to consider an external thunderbolt2 SSD drive enclosure to store your video on. I hope this helps, there are a lot of others more experienced here than I and I'm sure they'll have more info for you. I too wished I would have found vMix sooner, like before I bought all the similar stuff you're looking at. I could have bought enough PCIe cards to equal the TV studio input capacity for about the same money. Be well dear friend.

Have you already purchased all this equipment or is this just what you are thinking of getting? I think you will find it very advantageous to run everything on 1 computer and use vMix as the switcher. If you only have 2 cameras you can run the Magewell SDI>USB3 capture devices or Magewell HDMI>USB3 capture cards depending on what cameras you run. For our games on the road I use 2 of these plus run replays and 2 commentators on a laptop.

VMix runs well via bootcamp on the Macbook Pros, well as well as it does on most PCs with the same specs. (Those are well spec laptop).

You can use more than one Wowza server, you just have to pay for the extra license.

You could either stream to both Wowza Servers. Or it maybe more efficient for your laptop to have Wowza server 1, push publish a feed to Wowza server 2.

I use Wowza to push publish to Youtube live all the time. So Wowza is great for low latency streaming. Youtube live is great for long term storage/playback of your stream, a backup in case your Wowza server is having a bad day and well.. You don't pay for the bandwidth from Youtube --> The Masses :):):)

Now the Macbook Pro has 2 Thunderbolt and 2 USB 3 Ports (no built in ethernet). You will find that your limiting factor. There are ways around.

I recommend getting a Thunderbolt 2 dock, which expands your usb ports, gives a ethernet. http://www.belkin.com/au/p/P-F4U085/ was the one that my team came up with after much research. We considered size, ports, weight etc..

So now you can add more Magewell USB 3 captures devices and maybe 1 x BM Mini Recorder to get loads of video into the vmix computer :) Just some ideas.. I've been down a similar road, not the same of course.
