Thanks :) I really hope I'll be able to get back at ConTeXt
development and/or other contributions to the TeX world.

An interesting approach. I really need to learn to use
setups.
In the end, as the layout specifications got defined more
accurately, it turns out the number and position of the
layer elements is much less flexible than I originally
thought, so I don't need this approach anymore, but I'll
keep it in mind for future needs.
One thing that I've noticed with repeating layers is that
they appear also on 'empty' pages (as in those left by
forcing an even or odd page). Is it possible to suppress
then in those cases? Do the blank pages left by these
commands have a particular setup that can be tweaked?

This is how I would do it. Not sure if this is the best way. Use
tokens to keep track of the current information that should go to the
layer, and repeat the layer on each page.
\newtoks\testtoks
\definelayer[test]
[ width=\paperwidth,
height=\paperheight,
]
\startsetups make:test
\setlayer[test][x=5cm,y=3cm]{\framed[align=normal,width=5cm]{\the\testtoks}}
\stopsetups
\setupbackgrounds[page][setups=make:test,background=test]
\starttext
\testtoks{This is a test}
Let's see
\page
Now add something to the layer
\input knuth
\appendtoks \endgraf \input tufte \to \testtoks
\page
Let's start all over again
\testtoks {Testing again}
\stoptext
HTH,
Aditya

Sorry for that. Too much GUI (graphical user interface) stuff in my
work... :)

Excellent, thanks.
BTW, just to show how out of the loop I am, where can I get
the Details manual? :D

use a collector (Details, p.75) instead; I have no experience with them,
but setup should be the same as for layer.
