Sorry for the slow progress, everyone. I've always meant to incorporate 
mathversion support into unicode-math but its scope grew larger than my 
allowable time... Ulrike's and Ulrik's code looks just the ticket.

I've saved your code for building into unicode-math proper; rather than 
a separate command, I suspect it'll use some sort of optional spec, 
such as:

    \setmathfont[version=bold]{...}

Many thanks for forging the way ahead!

P.S.  Now that I write it, "forge the way ahead" seems like an odd turn 
of phrase.

P.P.S. I don't always follow this list very closely so anything useful 
like this please send to me directly if it seems worthwhile.

P.P.P.S. unicode-math was just updated in CTAN so it'll appear in tlmgr 
shortly, I suspect. I hope it should now work out of the box, but I've 
been wrong before. Sorry for any inconvenience with that over the last 
little while.
