Hi, Michael.

I have not yet checked the Linux Libertine packages, but this O thing is
a detail that I want to get rid of.

IMVHO, all these {otf,ttf,t1} prefixes are just a matter of
implementation details that should not matter to the end user. Of
course, the "should not" part is important, since we may still have
applications with problems with OpenType fonts.

OTOH, sticking with limited TTF and T1 fonts encoded in a myriad of
"standards" is a pain and just migrating to OTF seems to be the sane way
to go.

A good thing to avoid these kludges would be to generate two packages
from the Linux Libertine fonts: the ttf and the otf flavors.

Anything that breaks TeX is serious. :-)

Right. Breaking documents that people may exchange is very undesired.

If I am not mistaken, XeTeX uses fontconfig and LuaTeX use(d?)
fontforge's font loading mechanisms. It seems that LuaTeX is migrating
from fontforge (has already?).
