text chars in math fonts

[karl@cs.umb.edu (Karl Berry)]

I like the idea of a second text ``complement'' font more than 
sticking text characters into the math fonts.  I'm sorry I didn't
make that clear in my previous message.

I wonder if there is some way to modify TeX so that it doesn't
store all of the TFM file when it opens the font, instead loading
the characters on demand.  This would be a user-invisible change,
as far as I could tell.  Then the restricted font memory wouldn't
be a problem.
