That is true. Fortunately for instance the Spyglas Mosaic-browser,
included in Windows-95 (hope it will be there...) supports
local forms. So, you dont need script-programming to make forms. That
helps a lot.

Latest Netscape for Win supports dynamic documents too.

New features will emerge all the time; in year or two WWW is different,
developers should count on development going on. We will see 3D-interface
to WWW soon (already available for SGI). I can imagine that topic like
protein structures could make much use of it. The impression I got in 3rd
WWW-conference (have a look at
was, that much effort is put on to make WWW to coopertive (interactive !)
tool - not just tool for storing, delivering and searching information.
Much work is done on authoring/publishing in the Web. WWW-e-mail
-interface like one made for this conference is one example. As you wrote,
almost everything can already be done through helper applications. I share
the opinions, that WWW will be in the (near) future technology to connect
(Inter)net, what ever you are going to do through it.

The speed of the net is a different (though related) question. I believe
the commercialization of the net helps to make the investments in bandwith
needed and, what is important, to get reasonable rated access available
for everybody (except in the third world...).
