I'll try to finish a new release of the `concmath' fonts over the
weekend.  During this week, I was still revising the documentation,
although the fonts themselvers are ready.

I think we'll sooner or later have to reconsider the contents of MSP.
As for the exoctic glyphs in MC, I'd propose to take them out and put
them ``on hold'' until it is clarified who really needs them and why.
(BTW, what are the chances of rearranging MS1/MS2 so that the slots
0-31 remain empty except for dotless i/j and perhaps math accents.)

AFAIK, Unicode has slots for double and triple prime and backprime.
I'm not sure if the original idea was to reserve slots for those and
access them through ligatures if a font provides them.  Since most
of the existing fonts do not provide them, I wonder if it is really
such a good idea to waste valuable slots this way.

I'm not really sure of that myself.  Perhaps it would be better to
stick with what you have until we have further investigated other
alternatives for upright greek.  I remember that I brought up the
suggestion of using the greek/kelly fonts, which also were derived
from upright CM and some hackery.  Perhaps I shold compare that
approach and my work to distill whatever works best of both. 

Cheers, Ulrik.

P.S. Still another question: Should the \backepsilon be included 
in both upright and italics greek?  I'm unfamilar with who uses 
this symbol and what for.  (Adobe Symbol calls it `suchthat'.)
