Actually, B-MAC *is* in there, because the heart of B-MAC is the
flexible control interfaces to the radio, not exact method of preamble
sampling.  The preamble sampling, as per the original publication, can
be optimized in numerous ways and still be B-MAC, including sending
cyclical packets as is done in TinyOS 2.x (see Section 8 of the B-MAC
publication).
