That depends more on whether your algorithm is easily distributed. If it is, zeromq will be good for you.
I am currently using it to transfer model parameters learned on machine #1 to machine #2 where real time prediction takes place. The predictions are then sent out via 0mq to a robot controller.
The great thing of building systems with 0mq is that you just add another component without having to think too much about 'but then I will have to implement a protocol for it and HTTP will probably to slow and the request/reply pattern doesn't really fit there blabla'.
