> your OS guaranteed support for a "virtual architecture"
IBM i (the OS formerly known as OS/400) and TIMI say hi. Under the hood it gets transparently recompiled to the target architecture. "Customers were able to save programs off their CISC AS/400s, restore them on their new RISC AS/400s, and the programs would run. Not only did they run, but they were fully 64-bit programs."
