Remove fixed coupling to ipaaca #16
Description
Ipaaca is not really intended for just sending plain messages (numbers) back and forth (although it is quite frequently used in this way) and there exist many other middlewares (e.g. rsb, ros, protobuf, sockets, http etc). If we could find a way of decoupling the actual middleware receiver from the rest of the visualization, we could provide the same visualization utility for a bunch of different usecases, potentially with at most the extra overhead of having to write the specific receiver and potentially transforming the data in appropriate formats.
