It is worth noting that you could test with the existing overlay network tooling that the infra team provides. This has been proven to work over years of multinode testing. Then we could incrementally improve it to address some of the deficiencies you have pointed out with it.

This was sort of what I was trying to get across on IRC. Rather than go and reinvent the wheel to the detriment of meeting this goal on time: instead use what is there and works. Then improve what is there over time.
