Directory entries are stored in a B-tree, sorted in part on the case-insensitive name. If you make the names in the B-tree keys case sensitive, your sort order will be different, and you'll be incompatible with existing HFS or HFS Plus volumes. If you want to experiment with this, I strongly suggest using a different signature word.
It can be newfs-time option. Case-sensitive HFS+ volumes can have different signature in MBR (or whatever partitioning scheme is used on that hardware platform). There is a plenty of variants.
BTW, correct me if I'm wrong, but a new signature (HFS has it at the first two bytes of its volume header) and a change to the function for comparing two Unicode keys (so it will compare them respecting case) is all that is needed to make a case-sensitive variant of HFS. Of course, the utilities (fsck_hfs in particular) should be changed, too.
Case sensitive on storage, case insensitive on lookup only works if the lookup happens with knowledge of the case insensitivity.
I rather expect that HFS/HFS+ does it's globbing in the kernel, too, unless it depends on iteration. So that would be another difference, as well.
I guess the alternative to that would be to iterate everything, and apply the case insensitivity algorithm in the shell, too, but that would probably be error-prone. From my own memory of HFS usage on MacOS, the globbing is in the kernel.
BTW: The NTFS/FAT32 has this same feature under Windows, at least as far as that goes, e.g.:
C:\>cd "Program FILES" C:\Program Files>
So technically, it should probably be handed the same way for those two FS's. 8-).
