Is there a serious problem with node location stability? Oskar's simulations suggest not. Anything which impacts location swapping will need to be simulated, of course.
My main concern with treating offline nodes as online for purposes of swapping is that swaps cannot involve those offline nodes; they are static for the period while they are offline, this may not be good for location swapping.
