I think that was you, and I think it was for gluing the classes in NMEA together.

I'm not sure what a factory that takes a factory is. I'd think it's something that implements IPositioningProvider (eg a class) and then returns the instance? > If it's a thing that creates IPositionReceivers, it should return an > IPositionReceiver and take some description of where the position data is > coming from.

Would this be the correct place to implement behavior like "listen on a bunch of serial ports, until you find something that spews things that look like NMEA at you", or should that be another level of abstraction up? Would there be multiple such factories for different kinds of positioning? I don't know what cell ID will need to know to set up an IPositioningProvider, but the NMEA factory and gpsd factory need completely different kinds of information, for example.
