Have you looked at modes? I use this technique for making manuscript,
presentation and speakernotes versions of teaching documents.
Here is an example:
%%% TheEarthWorks.tex ---
%% Author: rma...@mun.ca
%% Version: $Id: TheEarthWorks.tex,v 0.0 2009/01/14 19:16:14 rmason Exp$
% Styles specific to the pres and MS modes:
\input presentation.tex
\input manuscript.tex
\starttext
\startcolor[TextColor]
\setupalign[right, nothyphenated]
\setuptolerance[horizontal,verytolerant]

\section{Introduction}
The Earth is made of rocks and in turn the rocks are made of minerals.
Most gems (\in{Fig.}[fig:intro]) are minerals. We will look at rocks
and minerals soon, but before we do so it is useful to have an
overview of the bigger picture: the structure of the Earth. We will
then go on to look at how various kinds of rocks are formed before
focusing on minerals and gems.

\section{Structure of the Earth}
What is the interior of the Earth like? Is it structureless, like
Christmas cake, or does it have a structure, like layer cake? If
the Earth is structureless then maybe gems can form and be found
anywhere. If it has structure then perhaps specific gems form
only in particular places.

Various lines of evidence show that Earth is a layered planet
(\in{Fig.}[fig:earthstructure]). The outermost layer is the
\emph{crust}, which is made largely of rocks and minerals that
have low density.

The next layer inwards is the \emph{mantle} which occupies a
large portion of the volume of the Earth and is made of rocks
and minerals with a density around twice that of the crust.
Beneath the mantle is the core, which is subdivided into the
\emph{outer core}, which is liquid and the \emph{inner core}
which is solid. The core has a density about twice that of
the mantle. The layering then is by {\em density} and it
increases as the centre of the Earth is approached.
Tha majority of gems are found, and originated in, the crust
(\in{Fig.}[fig:earthstructure]). Diamonds are an exception, having
been formed in the upper mantle. The gemstone {\em peridot} (a form
of the mineral {\em olivine}) can also be formed in the mantle and
incorporated in the crust in the form of \emph{peridotite}
inclusions that are brought up in some volcanic eruptions.
There is no evidence that material from the core reaches the Earth's
surface. However, we do have material similar to the material of
the core in the form of {\em iron} and \emph{stony-iron} meteorites
(\in{Fig.}[fig:meteorites]). Fewer than 100 stony-irons are known
and they are commercially and scientifically valuable. The
``stony'' component is olivine, often peridot quality. The iron
component is an iron-nickel alloy.
\stopmode%[manuscript]
The \input *.tex documents contain definitions used in the text. The
document is then compiled using a command:
texexec --mode=manuscript --result=EarthWorksMS.pdf TheEarthWorks.tex
When i want the presentation version I just change to
--mode=presentation on the command line.
Cheers,
Roger
