Welcome @cndolo!
Happy to record traffic for a while on the two https://demo.peer.observer nodes I’m running! Both of them have v2 and v1 transport peers as well as usually full inbound slots.
I just started a capture with the command you provided. I will figure out a way to get this to you.
Once you’re done with the paper, feel free to post it in the research section (Research - Bitcoin Network Operations Collective) or in this thread. I think you’ll find a few interested readers here!
