Question / Help How can I "Dual Stream"?

Ok, so me and my friend are trying to do this thing we believe is called "Dual Streaming". Basically what we want to do is this:
He broadcasts to my computer (or something), then I take his stream as a video input and put it in my live-stream canvas. This way, when I'm live-streaming, viewers can see both my screen and his screen simultaneously (without having both his twitch and mine open at once).

I was able to do something similar to this with X-Split, but it would be my friend screen-sharing via Skype and I just crop the window capture to show only the screen share.

This is currently how I'm looking at it; there are apps that will act like a remote webcam, they stream to LAN and you use a program on the PC to take the input of the webcam from the network. There are several iPhone apps that I know of that work like this. Is this a similar process to "Dual Streaming" and/or is-it/can-be done in a similar way?

I hope this helps explain, If you need me to try to explain better just ask.

You can just setup a local nginx-rtmp server under your Windows system. Your friend streams directly to this and with the browser plugin you can grab it from the server to incorporate it into OBS. Synchronizing both streams might get complicated though.

I actually wanted to do a tutorial with exactly your setup idea, but my university work keeps me from doing it atm :/
