> BDD means testing that you've delivered what the customer asked for.

No, that's "Acceptance testing", and doing it without TDD is actually quite common.

... which is why you frequently hear BDD called "Agile Acceptance Testing"

Perhaps by later practitioners of BDD who have no idea what they're talking about...

RSpec itself is in fact driven by the BDD ideas - adapting the language to make "doing the right thing" easier, and focusing on testing behaviour rather than state. RSpec has little or nothing to do with acceptance testing. It is thoroughly a unit testing tool.
