I saw where you are working out how do to the mesh networking with the frequency hopping. Something I've been wondering is how the mesh might work if you more than one project in close proximity. I know there probably isn't an answer to this yet, but would be interested to hear any thoughts - or maybe prod some discussions on it.
Might be better if I try an example. If I have a few boards working together in a mesh for Project A. Someone working with Project X and their few boards in a mesh happens to come within range. Will the boards in Project A start trying to mesh with boards in Project B? Would there be no interaction unless there were orphans?
I can see benefits if they do form one larger mesh, can see problems as well.
Another way of asking might be, what happens when you have multiple Scouts all driving around at the same time?
