Regarding 2: The DWF is more like and electronic plot than a DWG, which may
explain how it appears in the OpenDWG tool(view)kit. DWF is an electronic
archiving format -- that is, it contains only the information the author
chooses to publish (unlike a DWG). It's better than rasters (TIFF, JPG, etc.)
because it is vectors; is much smaller than a PDF; searchable; indexable; etc.
etc. etc. Once a DWG is converted to DWF, it is basically impossible to get
back to a usable DWG.
That sounds like marketing, but I'm just trying to be informative.

2) DWF: The openDWG alliance does have an interface module that can be
downloaded which is supposed to interface with the sources that need to be
downloaded from Autodesk to provide DWF input and output. I note that the
module is part of the Viewkit, not the Toolkit, so whatever input and output
occurs from this module will deal with pixels on the screen and not the
underlying structure of the DWG file.
3) How to do it: I don't think there are really any licensing issues here.
Basically Autodesk still holds the license to their piece, I just write a GPL
code to interface with it. OpenDWG also provides a script file to convert
source code (I am not sure if it is theirs or Autodesk's) into something
that Linux can handle. When I saw that I kind of said "I don't need this
right now", I have my hands full just trying to get the program to compile
for users of gcc 3x. There seems to be enough interest however so I can
certainly put it on the list of things to get to. I was about ready to
declare this project done, but I should be able to deal with one more piece.
