While I agree with Paul that cascading on top of an arbitrary stylesheet
is unlikely to be useful, I don't agree that that makes cascading
useless.  On the contrary, it still leaves cascading on top of a *known*
stylesheet as a viable and useful capability.  In the open Internet,
that capability will be of limited utility until a few common
stylesheets come to dominate net publishing; I suspect that will take a
couple of years, but I'm reasonably confident it will happen.  In
intranets, however, the ability to have a corporate stylesheet and
cascade divisional, group, and personal stylesheets on top of it would be
immediately useful.

I'd like to see someone develop good tools for automatic generation of
overlay stylesheets - a tool that would put up, for instance, all of the
unique fonts and colors that it would use based on an input cascade,
which the user could then manipulate for personal preferences and save
as the personal stylesheet to use whenever that underlying cascade is
seen.  I think you could develop a tool that showed all the unique cases
in a sample (greeked) document and allowed the user to click an element
to change it, with a feasible amount of work.
