    Man, a kernel-like thing that drivers/module code can be built against seems potentially great for improving security, letting less-privileged users do more things, fuzzing like this, etc. There is a little more about the idea on the NetBSD wiki, a standalone site (with interesting looking links), and Wikipedia.

    Is there any work towards something like this in Linux-land? I know about FUSE, but I’m more thinking of imitating the kernel interface presented to native drivers etc., whether through specially compiled kernel-ish binaries or tricks with VMs or what.
