You cannot compare IPF format to HTML. You should compare it to RTF or PDF
or something similar.

The HTML format is the most verbose, but this is because it intended as an
on-line viewing system. The RTF/PDF whatnot are meant for printing. If
graeme based IPF on the linear writer, then it will be meant for printing 
as well.
