Thanks Marcus!

I did run across Vmix in my searches. I'll have to kick the tires on that and check it out.

So obviously off topic and nothing to do with Avid, but anyway...
Bizarrely you missed the one solution I thought of, and have been using
for the last few weeks: vMix
Whilst the easiest set up is not to use NDI, and if it were coming from
a laptop webcam or mobile front facing camera would you need to? But to
use its own vMix call. This allows you to call (limited to 8) people and
have them set up as inputs to the vision mixer section.
There is the facility to record the inputs as individual tracks (thou
your machine will need quit a bit of power if you want to record 8hd
streams at once!)
PowerPoint, it can accept it as a file and play through it or you could
also use this as a call input under a sort of shared screen. If it were
local to the control room then you should be able to output this as an
NDI stream.
If you really do want to do NDI across the internet you will need a
hefty internet connection:
https://support.newtek.com/hc/en-us/articles/217662708-NDI-Network-Bandwidth
"NDI operates most efficiently in a dedicated network with high
bandwidth and high availability. This is in contrast to unmanaged
environments such as the public Internet or networks where video rides
along with data without priority.
While a single stream of HD video can easily be delivered on a Fast
Ethernet (100 Mbps) network, Gigabit (1000 Mbps) networks are essential
in production workflows. A typical NDI stream consisting of 1080i HD
video yields a data rate up to 100 Mbps per stream. This extremely
efficient stream is designed to have very low latency and allows
multiple streams to be stacked together on a single Gigabit network.
So with your 3 speakers and power point that's about 400Mbps coming
in..... And each of your 3 speakers will need 100Mbps out! Again,
probably not worth it for a laptop webcam.
And best of all.. The lovely people at vMix:

Have extended their 60 day fully functioning trial to 90 days in
response to the global pandemic.
Hope this helps,
Marcus
