Sylvestre, one of the problems with fuse itself is that it's GPL licensed, and not appropriate for inclusion in base. If you've got interets and talent in this area, you might want to consider having a peek at puffs (and refuse) from netbsd which has a workable license and could be included in base. I would definitely help if you're interested...
