I am working on adapting my javascript code to implement the direct mapping stuff. I am roughly half way through it, but I am not sure I can finish it this week, there are some high priority issues coming up this week...

But I truest some prototype will be available for the F2F. The code is merged with the previous version using the simple templates: if there are mustache like templates, they will be used, otherwise the direct mapping as a fallback. At least that is the plan...
