How did you use Palatino in LaTeX on one hand, and XeLaTeX on the  
other hand? The Palatino support in LaTeX (I assumed you used the  
mathpazo package) relies on virtual fonts and specially built metrics  
based on fontinst. The Palatino support in XeLaTeX (I assumed you  
used the fontspec package) relies on the OS X notion of a font, which  
is fundamentally different. Is this what you did?

I assume it would take OpenType, which LaTeX and XeLaTeX both support  
(through different mechanisms), to get some sort of convergence,  
given the various characteristics of the font (regarding metrics in  
particular) would be the same in both cases. Or am I mistaken?
