(I kind-of figure this is a rhetorical question, so this is a rhetorical
answer ;-)

Yes/no. For certain OS, there is little/no user structure with a root or
admin and general user=root

If the network is a switched network between the two hosts, then you have
a higher level of security from sniffing since the sniffer would see
nothing but the first ethernet frame from unknown MAC to unknown
MAC/Broadcast MAC unless the switch was configured (puposefully) to flood
to a sniffer-port with a sniffer running on it, or "break" the switch and
make it into a repeater and then see all traffic (prob result in a
RMON/SNMP trap/trigger if the switch was well set up and notify the
network admin) and then have a sniffer on one of those ports being
