It would be nice if we could bypass minimongo completely and dump the publication data directly into the store. I think your implementation is fine, but I see the duplication of state in minimongo and redux kind of a hassle.

An alternative is to replace the subscription with a method in your implementation. And when your components receiveProps, redispatch. You could make a High Order Component to generalize this pattern across components.

But thats just a thought! Your solution is good too
