I'd like to separate Bi-directional RPC and Bi-directional network
connection.
Of course Bi directional RPC of course gives lots of benefits. But
Bi-directional network connection requirement is not the benefit i can think
of. So i was curious how we can simplify connection requirement while having
benefit of bi-directional rpc capability.---
