SPONSORSHIP OFFER: centering a context between two other contexts

[Kieren MacMillan]

Hello all,

I would pay pretty good money for a *real* solution to the problem of  
centering one context between two others...

In particular, the solution I'm envisioning would solve, once and for  
all, the age-old "piano with centred dynamics" problem -- right now,  
I'm fighting with that, and it's frustrating.

Of course, the ultimate solution would also be immediately applicable  
to:
    placing text/performance instructions between staves;
    setting a single line of lyrics between two vocal/choral lines;
    etc.

Any takers and/or cosponsors?
Kieren.
