I have looked at both Gardner Read and Gould.

Gardner Read gives several examples from Bartok's Mikrokosmos (e.g. 
Mikrokosmos No.44 where the first piano has the key signature fis-gis, 
in the right hand with treble clef both are placed at the second staff 
line from the bottom, in the left hand with  bass key they are placed at 
the second staff line from the top - like Roger does in his example in 
the second system).
He does not speak at all about the validity of the accidentals to other 
octaves, but I understand this as silently implying they are valid vor 
all octaves.

Elane Gould says on p.94 in the section "Key signature in non-tonal or 
polytonal music - Unconventional Key Signatures":
"Any sharp of flat may be selected as a key signature to alter all 
octaves of the selected pitches."
(She also gives an explicit example, a scan of this section is attached)


I couldn't find any reference to an accidental only applying to the one 
particular octave it is printed in.

So, basically, I couldn't find any reference where an accidental would 
only apply to one octave. Rather, everything in those two standard 
references points to validity in all octaves...

Of course, I don't know if any really modern composer already takes 
advantage of lilypond's current way (accidental applies only to the 
printed octave)...

Cheers,
Reinhold
