Japanese was working more or less a few months ago. I guess vertical
typesetting is a little more involved, but as far as horizontal
typesetting goes, most of the spacing is coded into the font already
(monospacing). When the Latin alphabet enters, as is becoming more and
more common, especially in technical literature, the monospacing breaks
down, and common practice is to just typeset paragraphs in block form,
adding the necessary spacing.

Typescripts are already working wonderfully in ConTeXt (thank you!), so
for now it should be only a matter of supporting the characters.

I don't know what character categories and initializations are, but if I
can be of any help, please let me know.

It was working till February (I tested it with a old beta) and
also when i comment the mentioned but i have no clue what’s the
purpose of the line.

ConTeXt MkIV doesn’t support vertical writing but with a little
bit of TeX knowledge it’s possible to add it, the result is not
perfect [1] (there is no space between the characters) but it
shows it can be done.

But it wouldn’t harm when ConTeXt would support monospaced output,
proportional spacing seems to be for the moment the only format.

just use columnsets with 1em width columns

This is no option when quotation marks are used and other characters
which can’t be broken at the end of line. Another advantage of LuaTeX’s
vertical mode is that you can use \underbar and other commands which
aren’t possible with columnsets.

The output in my example would be nicer when the width (or height?)
of each character had been 1em (or more).

if used at all; if I'm right vertical does not mean that all such 
properties 'rotate'

It depends on what one wants. Using the vertical (rotated) variant in 
it's simple (traditional) way proably can work at some point (but it 
needs to be properly integrated in the page builder then and we probably 
should forget about figure placement and display environments 
(starttyping etc).

If one just wants vertical stacking (with quad*quad characters) then 
columnsets are a nice way in between as then we can still use figures).

Anyway, a proper model is needed, not some ad-hoc hackery.
