apple has in fact documented hfs+ fairly well (from what hasi has
said).  however documentation alone a kernel space filesystem driver
does not make.

writing filesystem drivers is rather difficult, and generally not very
fun from what i hear.  of course it depends on the filesystem too,
there are lots of people who seem to enjoy working on things like xfs
and reiserfs...  from everything ive read from people who worked on
hfs+ its not a pleasant thing to deal with.  

its just hard to motivate oneself to work on a crappy filesystem that
will never be used mainstream (unlike ext2, ext3, xfs etc).

the read-write support doesn't extend to the OpenStep UFS varient,
which is what apple uses, so for now its readonly.  but thats much
better then nothing, which is what hfs+ is.

the old HFS will do this for you, though linux will corrupt it
regularly, and ive read OSX doesn't deal well with HFS in the gui, so
you would have to do all file managment in the shell.

at this point its a `then do it yourself' ;-)
