I have tried it (seems without success):
# ls -la /bin/rcp
-r-sr-xr-x 1 root wheel 244872 Feb 17 13:51
Python 2.2 (#1, Mar 20 2002, 13:17:06)
[GCC 2.95.3 20010315 (release) [FreeBSD]] on freebsd4
Type "help", "copyright", "credits" or "license" for
>>> import os
Traceback (most recent call last):
File "<stdin>", line 1, in ?
OSError: [Errno 1] Operation not permitted: '/bin/rcp'
The same as non-root user.
