What superscalar and out-of-order processors are exploiting is instruction level parallelism, while their technology seems to use thread level speculation.

That's most likely the case, but I wouldn't consider it cheating. As long as from the software perspective only a single thread is running (and SPEC CPU 2000 and 2006 are single threaded), I think it's fair game. The whole point of their project is to expose parallelism without requiring the programmer / execution environment to explicitly support it.
