I don't see why we can't do both.  HTML is already split into separate
levels/versions to allow for "what we want now" to be documented/implemented
while "what we want in the future" is being discussed.

Meanwhile, it would be useful for WWW browsers to handle the dvi format
if it is extended to handle hypertext links.  I am not convinced that
it can be done (LaTeX is pretty well fragmented already), but I would
still like to see someone try it.  However, HTML development should
not stop just because someone else thinks they have a "better way" --
implement the "way" first and then we'll decide if it's "better".

Not much work at all, though you will only get something readable if
that document uses true PostScript fonts (e.g. no bitmaps from metafont
translations).  Also, although the PDF spec is "open", it is still a
proprietary standard because Adobe controls its extensibility.

BTW, does anyone know where the current PDF spec is stored?  It does not
appear to be where I would expect it:
