Ah.... so  that's the problem.

Still, I'm curious: Would there be some way of getting XeTeX to treat the Lucida Bright tfm-based
fonts in the same way that it supports the Computer Modern fonts? If I typeset this, relying
solely on the tfm-based Lucida installation (from TUG):

%%

%!TEX TS-program = xelatex

\documentclass{article}

\RequirePackage[mathitalic2,expert,nolucidascale]{lucidabr}
\RequirePackage[T1]{fontenc}

\begin{document}

This is a simple finite test. $x^2+y^2=z^2$

\end{document}

%%

The math comes out right (in LB), but the text appears as a generic sans serif, meaning,
I take it, that the metrics were found (the 'fi' of 'finite' appears as a box in the preview)
but not the outlines...

So near and yet so far...
