That's pretty insecure. I've seen instances where people on our campus
(admittedly, a large one with relatively insecure systems anyway) have
had other people connect to their X displays because they'd done the
"xhost +" bit. Generally more a nuisance than a real security concern,
but still... "xhost + locahost" is only marginally more secure ... with
that one, just anyone on the x machine can connect ... so on a system
which distributes campus email, that's a few thousand people here...
Go for "sudo".
