Ok, I get what you want to avoid, though could be interesting to actually have
a fully-connected cluster in order to collect performance data on each comm.
pattern and see how significant the difference is for a variety of use-cases.
Do you have a particular example you can give where you’d use this BIF/function
to relay a broadcast from a worker to all other workers via a proxy?

global intermediate_store: Cluster::StoreInfo;
event bro_init()
{
intermediate_store =
Cluster::create_store(“ssl/validate-certs/intermediate_store");
}
And then port the rest of that script to use broker data store api
(get/put/exists calls) to access that store.
