i think that my hope was that with the link up
of netscape and adobe we would have a small window
like a present <IMG> which would contain the math fragment
then much less has to be shipped around.

indeed. (merely indeed!) in fact hyperdvi does more than this
and has linking within and between documents. see, for
example the los alamos e-print archive. exploiting, inter
alia, latex's mere cross referencing mechanism). 

i note that
mathcad is touting a new version which incorporates a
browser (if i read their advertising bumph aright).

if html3 merely managed to describe pictures of equations, it
would be doing much more than the draft indicates. if it simply
replicates tex/latex, it would enable tens of thousands of
documents to be effortlessly incorporated, and save thousands
of people from having to learn another (inadequate) notation.
