Well - anyone could compile a fresh version; or copy a version from
another machine into his home dir or /tmp; but if you ignore that type of
level of ability in your user a small obstacle would be:

	# ls -l /sbin/ping
	-r-sr-xr-x  1 root  wheel  421060 Apr 28 15:49 /sbin/ping
	# chmod a-rx /sbin/ping

which makes it executable only to the owner and those member of wheel.
Which users generally are not. But ping is not exactly a dangerous command
- so why worry about it ?
