Tao was a UK OS company that produced operating systems call Taos and intent (emphasis theirs); their killer feature was binary portability and assymetric multiprocessing, so you could have multiprocessor machines built of several different random architectures and treat them all as a single message-passing system. Code was converted from bytecode to native machine code at load time. It was small, elegant and very cool. Turns out people didn't want to buy that.
