10 megabytes is quite tight restriction. I recommend you
to consider the subsetting of CJK ideographs to each
localization.

Please take a look on "Wen Quen Yi" http://wqy.sourceforge.ne
t/
it is GPLed. Their goal is to provide a font covering
all CJKV ideographs, additional CJK characters (Bopomofo,
Hiragana/Katakana and precomposed Hangul), so their font
is quite huge. The size of TrueType font (without bitmap)
is 16MB. Also they provide bitmap only font: the size of
16x16 pixel font is 3MB in pcf format (if in pcf.gz, it is
reduced to 844KB).
As an example of subsetted case, I take "fansong
ti"
(gb16fs.pcf in X11): its coverage is GB2312 (the most basic
 character set in PRC), the size in pcf.gz is 247KB.
Anyway, I think WQY product is good starting point than
collecting various CJK fonts for various coverage.

Although FreeType2 is completely capable to handle WQY
fonts,
fontconfig cannot handle bitmap-only TTF or PCF, as you
know.

About Thai scripts, I have no idea on particular fonts to
recommend. Linux TLE (Thai Language Environment) project
may have some free fonts for the screen of desktop PC, but
I'm not sure bitmap font is used.

Thai Linux Working Group provides a set of fonts, sample
available on [1]
and downloadable in [2]. This set of fonts is available on
Debian and
Ubuntu, though I don't know the situation in other Linux
distro and Unices.

With 10MB limit, I'd say TTF for Chinese is not very
feasible, even when
subsetted as suggested by mpsuzuki. Better choose bitmap
fonts. WQY
is a good choice for simplified Chinese, though its
traditional Chinese part
has some glitches. OTOH, another set of fonts created by
Firefly [4] has
good trad. Chinese support but will never cover simplified
Chinese.

Situation is better for Korean. There is a set of Korean
fonts of high quality,
called UnFonts [3]. The largest TTF in the font suite is
4MB, though UnBatang
is recommended, which is about 3.5MB. Also packaged in some
Linux distro.

  Firefly renamed the font to opendesktop fonts includeing
Sung and Kai.

  And it include both Traditional and Simlified Chinese.

  odosung.ttc      32738168 bytes
  odosung-ExtB.ttf 96020 bytes
  odokai.ttf       12464296 bytes
