Hi Florin, Thank you for your reply!
"For instance, running apps within the vms that attach to their respective vpps via vcl and then report their connections to a central point, over the network (so potentially over vcl), should be possible." This is partially of the intention. To be clearer, what those vpps on different vms do, can be just all process network packets (setup/teardown sessions) applying some firewall rules, behind a load balancer, the central managed "controller" will host the one big session table with certain network resources (i.e. IPs) under single policy across all the vpps over different vms. Hope this helps you understand better, is that feasible?
