my friend lukas and I were fucking around with feedback routing between computers over the internet using a software for live audio streaming called sonobus it was really fun and quite funny, so we got some other people to join in, manifesting in a feedback loop between 7 people, each with different processing chains on the audio. In terms of routing, i'm pretty sure this could be modelled as a 7x7 feedback delay network, where each channel feeds into the six others but not directly into itself. see this explanation of FDNs for context
