The layout is the exactly the same if you are using a relative directional
system (before/after, start/end of line instead of top/bottom, left/right of
line). So, for RTL, the bullets and indentation are on the right edge, for
TTB vertical layout they are along the top edge.

Chinese words average 2 characters long. Japanese and Korean are, I believe,
a bit longer due to inflection (but I have not studied these languages).

Same as in horizontal. There are special considerations for CJK in general,
however.

There must be enough leading between the lines to accomodate ruby annotations.
And of course, your layout engine must support ruby annotations. :)

Putting out a wild guess here, but I think underlining is generally positioned
such that it is noticeable.

A vertically-set document would be reasonably readable only if
   - it scrolls only horizontally
or
   - it scrolls only vertically, but it's multicol and the columns are
     no broader and no longer than the viewport

It is analogous to saying that a horizontally-set document would be
reasonably readable only if
   - it scrolls only vertically
or
   - it scrolls only horizontally, but it's multicol and the columns
     are no wider and no taller than the viewport

In print, most aspects of vertical layout are analogous to horizontal
layout. The differences are mainly in the details. (Vertical layout
usually has more separation between lines, Chinese uses a different
set of quotation marks, you can use a vertically-compacted font style,
etc.) Another thing to note is that Japanese magazines make frequent
use of mixed layout pages: pages with some boxes laid out horizontally
and others vertically.

One major difference between vertical and horizontal layout is that
vertical layout can stack its lines from right to left (as for CJK)
or from left to right (as for Mongolian and Manchu), whereas horizontal
layout never goes from bottom to top.
