 xhost is _host_ based access control, so of course xhost +username doesn't
work!  Debian by default starts X servers with -nolisten tcp, so doing xhost +
(to allow all connections) is the same as xhost +localhost, and is ok if
(and _only_ if) there are no local users you don't absolutely trust
(including trusting them not to get their accounts cracked with bad

 I emphatically do not recommend using ssh running X stuff as root.  That is
_huge_ overhead compared to unix sockets and shared memory!  (If it's
working fine for you, then whatever, do what's easiest for you, but if
you're going to go to the trouble of learning how to jump through a hoop to
get X working, pick the right hoop!)
