There is math upright in some fonts (Lucida Expert, for example). I
use them for getting upright ¹, e and i, in particular, based on the
requirements of some journals which want upright letters for all math

I think nothing proper will come out before Unicode math fonts are
released. Using virtual fonts with XeTeX being out of the question,
the solution could come from the Mathematica fonts, or from the STIX
fonts, now announced for the end of this year <http://
www.stixfonts.org/>. But that would also require fundamental changes
in TeX, which seems even more firmly grounded in 8- (or even 7-) bit
world for maths than for text. Or could this come from ConTeXt?
