Indeed, this is why the RPC interface is engine-to-engine.  There is
an engine sitting at the "server" and an engine sitting at the client.
The former is just a network daemon, the latter is connected to the
client's UI.  Two two engines talk to each other via an RPC protocol
to keep data consistent (or make requests/queries/updates/etc).
