Project Mars — not chocolate?

The announcements just keep coming from Adobe today:

Mars is the code name for technology being developed by Adobe that provides an Extensible Markup Language (XML)-based representation of Portable Document Format (PDF) documents. (Mars page at Adobe Labs)

In the long term, I think this means the Death of Distiller. Other than that, I think my brain has gone into information overload.

Any thoughts on where this is going?
