This is fantastic, except for the fact that it's abstracted by something
called puffs.  I took a look at the NetBSD source code for this
(src/usr.sbin/puffs/mount_sysctlfs, tag netbsd-5) and puffs is
absolutely required for it to work.

http://netbsd.gw.com/cgi-bin/man-cgi?puffs+3+NetBSD-current

Simply put, someone would have to port puffs for mount_sysctlfs to work
on FreeBSD.  There is already efforts underway to do that, but I have
absolutely no idea what the status of it is:
