@jace:

The disparity with our markup is okay. Merely using CM6 with GFM mode is a sufficient goal.

We will evaluate how granularly configurable CM6 config is. If this is doable out of the box, we could consider it or else deprioritize it further.

Ixora looks great. If it's stable on mobile browsers, we should use it.
