Fuse4X – The Easiest and Fastest Way to Create File Systems for Mac OS X. MacFuse is currently going the way of the dodo, so there's a need for an alternative if you want to load userspace filesystems (e.g., if you want to mount an SSH server). This version also looks more interesting than OSXFuse, because OSXFuse primarily aims for compatibility with the old MacFuse, while Fuse4X primarily aims for compatibility with the Linux reference and should make porting userspace filesystems easier.
