When it comes to LKMs, aren't they just for providing device drivers?
Loadable FSs, or even user-level ones (HURD's translators) is a nice
thought, but it isn't necessary unless you care for speed.  One can
always write a user level FS with a NFS server RPC interface (automounters
do this I believe).  Frank, I'll soon be uploading the NetBSD ADOSFS code
anyway, you can snatch it then and work away on r/w support if you want to.
