Piano Pedal performace across a PianoStaff

[Michael Welsh Duggan]

A pedal-event is currently performed by the staff context within
which it is declared.  As a piano's pedal tends to affect the entire
output of the piano and not just one hand, it would be nice if
pedal-events could be automatically performed across the staves in a
PianoStaff.  My instinct was to use the following:

        \context {
            \VoiceContext
            \remove "Piano_pedal_performer"
        }
        \context {
            \PianoStaffContext
            \consists "Piano_pedal_performer"
        }

but I can see that I was wrong.  What would be necessary to make
something like this work?  I am willing to code it, but I would
appreciate a push in the right direction.
