Understood. I was planning to spin up the server on a "proper" server machine and just use the Pi as a client (which is the metric I believe you're interested in). If public servers are available, I can just spin up two clients on Pis and give it a test calling between the two. I don't have many options for USB cameras but I can figure something out. I do have a CSI camera I can test on one Pi though. I've made a note to test this. I'll need some time as they're mounted in a server rack case I built and will need to be removed and re-installed with a DE to test at my desk.
