[FOSS-GPS] Tango/Foxtrot GPS - Plotting locations of

As for the suitability of my implementation, I don't think it would be useful because for my use case every node can be assumed to want to know the location of every other node. I also cannot really on the availability of a centralised server. I'm therefore just directly sharing the lat/lons between each user using multiple TCP sockets.
It's an implementation for quite a specific task that I don't think would translate for the general use case really.
