If you want to have some fun with filesystem-related things, then a very 
light supplemental patch might be needed for latest versions of the 
ntfs-3g project, as far as I remember from testing. It would need to 
have FUSE support, but optionalized (through good use of tunable policy 
which means do not allow by default the loading of fuse.ko kernel module 
and a few other related permissions that are only needed in FUSE 
supporting versions).
