for all appearances its abandoned. the only sign of anything
happening with it is someone starting a sourceforge account for it,
all this has is the very pre-alpha development code which pretty much
just spews errors and panics the kernel, the same code that was
released about a year ago or so.

apple always does HFS+ in a wonky way, they basically create a
ordinary HFS filesystem, then put a huge hidden file with an HFS+
filesystem on it, thier drivers notice this and mount the image rather
then the wrapper. when you tell linux to mount -t hfs whatever /mnt
you will see the HFS wrapper which won't have anything useful (usually
a README and a couple fake macos system files).

i don't know much about this, its probably not significant, certainly
not to linux since it has zero support for any revision of HFS+,
outside of the userland hfsplusutils.

don't hold your breath waiting for apple to help, im sure they want
nothing more then to keep this thing MacOSX only. if you live in the
US (or other country with questionable laws regarding these matters)
you may well want to consult a lawyer before doing any reverse
engineering, the DMCA (or some other rediculous law) may or may not be
an issue with this.
