Thad,
    You wanted a way to detect setuid programs, well here is a quick
script I tossed together for you.  I would of mailed it, but someone else
might find it useful also (who I don't know :-).

# issu
# by Cliff Skolnick (ccs@lazlo.UUCP)
#
# issu script to determin if a user is setuid or not
# note, if the shell itself is suid, it will not detect this.  You
# can check the number of fields returned by id if you want to add this
#
# Cheap and dirty way of seperating the output of id which encloses the
# uid in parenthesis.  Let the shell do it with it's field seperation
# variable
IFS=${IFS}"()"
set `id`
uid1=$2
# get who is logged in on the terminal
set `who am i`
uid2=$1
# if the user logged in does not match who is running this, then it
# is set uid.
if [ $uid1 = $uid2 ]
then
	echo "no"
	exit 0
else
	echo "yes"
	exit 1
fi
