Yet another shameless plug: SpaceBase[1] uses an R-Tree variant especially tailored to concurrent modifications. It does not require a global lock (as an R* tree would), while at the same time it does not degenerate over time.

It is used in real-time defense systems, MMOs, and real-time location-based services.
