I'd be against hwloc automatically spreading across multiple machines. I think there are plenty of tools to do that already.
That being said, having better support for being able to aggregate data from multiple hwloc instances (e.g., lstopo) on multiple machines into a single, cohesive map, would be great (waving hands here; I have no specific suggestions).
