Version 1.0. I was at The Foundry while this was happening. ILM struggled to use Katana with their existing file format. I'd be worried if the idea wasn't similar - it was the implementation that mattered, and ILM's older format wasn't very good at random access and lazy loading (which were things needed for efficient use in Katana). Alembic 1.0 was very close to Sony's Taco format rebranded.
