Well just put "noexec,nosuid,nodev" then.  That will work just fine and
won't allow the fs to be user-mountable.

Doesn't "nosuid" also turn off the sticky bit?  If so that would be a bad
idea for /tmp.  Those options might also interfere with programs that like
to create Unix socket files in /tmp. 

Also, you don't want "noexec" set for /home; otherwise users won't be able
to run their own binaries.  Are you really trying to be that draconian?  
I suppose that depending on your users it might be acceptable (you'd want
to put YOUR home directory somewhere other than /home in that situation).
