SPDY is here to increase efficiency between browser and server (this is sometimes called scaling). 'Dynamic network typologies' as presented is moving the network routing stack to a software CPU. Not sure I would bridge these two technologies together to solve my 'interesting worker topology patterns'. This is classic top down design.

Right, I'm not linking SPDY and "dynamic topologies". Rather, I'm linking the message-oriented communication of SPDY and 0MQ (and 0MQ is not the only way to achieve this).

Once a request enters your "back office" it should all be message oriented, over persistent connections, with flow control / QoS, and the like.
