To clarify:

peg-multimarkdown was derived from peg-markdown, not pandoc.

Ali Rantakari's work on his highlighter's PEG was also derived from peg-markdown, not pandoc.

Composer's highlighter is based on Ali's (which performed highlighting for markdown, not MMD). Composer will highlight MMD *or* MD, depending on preferences. I modified the PEG to support MMD syntax, and made some changes to the highlighter code itself to make it more flexible and to enable context-sensitve editing, and not just highlighting.

I am very thankful for the work by both John and Ali, as I would never have been able to complete my projects without their work.

As for whether MMD is emerging as the most popular markdown derivative or not, I have no idea. I have multiple search feeds that keep me informed about what people are saying about MMD, but I could be missing a lot of traffic talking about how good other implementations are.
