Message expiry *may* not turn out to be an issue for you depending on
how you want to map the RPC semantics. IIRC the Java RpcClient does
not have a client side timeout anyway, the invoker blocks
indefinitely. Message TTLs would be nice, but whether or not this is
strictly required will depend on your app.

Sure - the idea of the pattern is to temporally decouple the RPC
bottom half by making it asynchronous.
