Nope. You do "xhost +localhost", and that means that anyone on
localhost (127.0.0.1) can connect to the X server. If you do "xhost +",
then anyone anywhere can connect to the X server, and that *is* a
problem. Routers and cablemodems and such are supposed to block packets
with bogus source IPs like 127.N.N.N. You can always use iptables to
block packets with destination port 6000, as well.
