updates to DDP pages

[Adam Di Carlo <adam@onshore.com>]

I've updated a number of documents on the DDP pages, trying
frantically to get rid of the cruft and update the open issues
and topics.  A poor attempt so far.  Check it out.

Others with the competence and CVS access are also welcome 
to add / update more information.
