Well honestly I've always considered that  mount(8)  was  reserved  to
root. The man page doesn't state state it is, but that seems  more  or
less implicit. I may br wrong.

On the other hand the man page for mountd(8) states that for  non-root
mount  requests  to  be  accepted,  it  has  to be started with the -n

On  my  version  of FreeBSD (2.1-stable), the -mapall options seems to
have  different  semantics,  like  -mapall=user:group.  I'm not sure what you
expect  that /etc/exports file to do with -mapall=ip-address. Anyway I
can  see  that  allowing a non-root user to remote mount a fs exported
without the mapall option opens a major security  window !!
