Fedora considers removing NIS support

I wonder how difficult it would be to provide a completely separate daemon that transforms NIS into synthetic passwd/group/shadow files via FUSE, and then mount that over /etc/passwd and /etc/group and /etc/shadow at boot time? That would completely remove the need for special integration with authentication.

(You'd still need to use a separate tool like yppasswd to handle password/information changes, as well, unless you want to make that filesystem writable and try to interpret local writes. Probably safer to make the file read-only.)
