If the application has to handle this, then it could use a simple
client timeout on asynchronous RPC cycle - this is doable without
changing anything in the broker.
However, if you want delayed routing rules based on server side TTLs,
this will have to be implemented in the broker.

Sure, that's a plain jane priority queue and is currently in the
works. It is also part of the AMQP spec :-)
