No kidding?  I'm very surprised by that.  But I suppose it does make a
certain amount of sense.  The whole point is security, and xhost +
certainly doesn't provide any... :)

But what if I simultaneously am logged in on remotehost and have an active
X session?  Then my new Xauth file will overwrite my old one, and prevent
local clients from connecting, no?
