I'm really puzzled now.
Is this the same "paul van den berg" with whom I had a discussion about this
subject in 2006 when this document was created?
Also, the "paul van den berg" back then provided a pdf conversion of this document.
It is all available here:

  http://jpegclub.org/temp/
  http://jpegclub.org/temp/ITU-T-JPEG-Plus-Proposal_R3.doc

There have been more things happening in the meantime and other documents
being written (which are not publicly available) with more descriptions
and more discoveries described, but this one is still valid.

It is the entity which I took over from the previous IJG organizer Tom Lane.
The "group" was nothing more than a mailing list, and unfortunately it went
defunct some time back.  Then I tried to recover the list by taking it over
to my own site, but it turned out that the effort wasn't worth it because
there were no more substantial contributions.
And I think the group was not very helpful even before that happened - the
IJG libjpeg effort was basically the whole work of Tom Lane himself, and
now it is basically the whole work of myself.  There is no noticeable
support from anywhere, that's why Tom Lane couldn't continue the work.
I took it over because I made fundamental discoveries and contributions,
and nobody else was present to do that.
The missing support problem is still the same, but what can I do?
Either I do it, or nobody else will do it, and DCT-based JPEG, which is
the only proper base for image coding application, would die.

Yes, there are always many people demanding support, updates, and asking
questions, and I do my best to answer the questions and hint to solutions,
but there is no one who would provide any fund for doing this work.
There are many funds available, but, as said, they are actually all invested
in bogus developments.  This has to be understood.  And as long as this
situation continues, there can be no proper progress.

What I'm actually doing is to establish an enterprise for realizing the
discovered features in the movie coding domain!  There are much more
opportunities available in the movie coding.  The still image domain
is actually in complete darkness - all research, development, and
industry is corrupted in this area.
I have now found some kind of support for introducing the features for
movie coding applications, and if this goes well, I will also be able
to push the still image develeopment in the right direction.
