If we had HFS+ in the base it would do most of that other then the
encryption which would require a port of GBDE (though porting all of
GEOM isn't the only way to do that).  I've got a friend who uses HFS+ as
his PC/Mac compatability FS because it sucks less then FAT and there are
decent third party drivers for Windows.
