Can we have more NDI output streams? 8 would be perfect for my case. (I have vMix 4k)

I host zoom webinars with 2-3 speakers that split up in breakout rooms. Each speaker needs two NDI streams (full screen processed cam + cam + powerpoint). That would greatly benefit from a system with 6 NDI streams, on top of the Output signal. So, 8 NDI outputs would be great.

I realize this comes at the burden of extra CPU, GPU and network load. But my medium level Intel i7 laptop can deal with 4 NDI streams still decently and for my Ryzen 9 desktop it's simple. I did some experiments with OBS with 8 NDI output streams and that worked fine.

+1 on this; even one more NDI output would get us where we need to be. We understand the NDI network issue. But 90% of the time our setup is the following:
NDI2/BusA for remote Moderator
NDI3/BusB for remote Presenter channel 1
NDI4/BusC for remote Presenter channel 2

Presenter 1 and 2 slots get leapfrogged all day. They might be large groups, or single presenters; the outputs are basically limited by our mix-minus NDI returns.

What we lose is ability for an internal Producer / Green Room return. The current solution is that we have to run our fullscreen out multiview through an HDMI router and back into a WebPresenter or similar to be able to get one more output that we can send back out over the internet. Cannot use SRT or VCall options for this; it has to be Zoom, Teams, Webex or similar based on specific clients.

All of this is very simple with a conventional control room setup. We are just limited in Vmix by the number of NDI outs.

This is the same setup I have, but what I've started doing recently is using one NDI output for video return only, and then enable the audio-only NDI outputs for each of the mix-minus busses. Normally the video return feed is the same as program, so I have the remote moderator and presenters all seeing video from NDI 1/Output 1, and then each one gets their audio return from NDI Audio Bus A and so on. This eliminates sending multiple NDI streams carrying the same video data, and allows access to all 8 mix busses. The only thing is that you have to be able to pull in audio and video separately for your moderator/presenter feeds, but I've been using OBS as a more flexible version of NDI Virtual Camera to accomplish this.
