I don't have Berlin installed, and do not own Mac, but I indeed tested fonts 
from http://jhcloos.com/fonts/bdfttf/tests/
(URL posted by  "James H. Cloos Jr." <[EMAIL PROTECTED]>)
in Windows.

'ttfext' utility from MS correctly indetifies those fonts as TrueType fonts, 
and displayes all properties for them.
And it says that font has embedded bidmaps.
Unfortunately, I was not able to get sample page rendered for those font s- 
but I guess it's a Microsoft bug :-)

On the other hand, ftview (from FT 2.1.1) correctly displays bitmap Courier 
and Helvetcia at 8pt, 10pt, 12pt and 18pt - for *TrueType* font.
For OpenType - ftview displays nothing.
And I guess here that it's either FreeType bug (ftview bug), or PfaEdit bug 
(which exported something incorrectly...)

I think that we speak now about XFree86 running on Linux/FreeBSD.
While it's nice to make fonts compatible with other OSes, I doubt that we can 
fix MS Windows or MacOS or Adobe bugs.

If you think that people will take .ttf from XFree86 and install on Windows, 
and than complain that *your fonts do not work* - than I agree with you.
ButI doubt that ordinar Windows user will install XFree86 fonts on its machine 
(Windoze). 
Usually opposite process happens :-)
