Hi:

The LucidaMath fonts come with PL files (at least if you bought the fonts
from Adobe).  These should be good starting points for making TFM files.

The delimiters always coming out in the smallest size probably has to do
with the fact that, as you know, cmex10 is a complex combination of (a) a
font and (b) all sorts of hair for connecting related characters of
different sizes together.  Does your TFM file for LucidaMathExtended contain
information on the `extensible' characters, and those in an `ascending
sequences' of different sizes?  Again, the mentioned PL files contain what
you need to enforce this.

  (Knuth pulled a fast one when he called cmex, cmsy and cmmi `fonts' - 
  they actually contain all sorts of complex machinery normally not found 
  in a `font'). 

Regarding the problem of characters having coordinates larger than 2000
in Adobe's standard coordinate system:  cmex10 has the same problem.
It seems to me then a bug in VPtoVF if it can't handle such coordinates.

Kind regards and please let me know how it goes,  Berthold.

P.S. You may know that Ralph Youngen of AMS made up a math italic font using
a Times Roman italic (reported in TUGboat).  That is the only successful
effort of getting non-CM math fonts into TeX that I am aware off so far.
