Yes, this tests positive for Mac OS X (and probably other variants of 
Darwin).
Yes, Mac OS X uses a case preserving but insensitive file system by 
default (HFS+), but has case sensitive file systems (UFS, and a case 
sensitive version of HFS+, NFS, etc.).  The SF compile farm may use one 
of these alternative file systems, probably NFS if anything.

Yes, definitely.  I'm positive you can do this with CoreServices, but 
I'm not sure it's portable to Darwin (not Mac OS X).  I'm sure there is 
some Darwin-compatible way of doing it, but I don't know it off the top 
of my head.  I'll try to remember to look into it if nobody else finds 
it first.
