64-bit shared storage is actually a better fit (semantically) with what you're describing than dataspaces are. The 64-bit sharing and access mechanisms are more modern, sophisticated/useful. I have used dataspaces intensively since they were first made available but would never do so again. There's no compelling reason to change existing code that works, but for new development the space above the bar is the only logical choice. CC
