restrict x server access with xhost

[David selby]

I can enable other users to log into my x server with xhost +, I need to 
do this because I want ro run a program via user web crontab which uses 
xmessage.

Idealy I would like only root user to be able to access my x server ... 
(less users who can access it, more secure ... rule of thumb) so I tried ...

[EMAIL PROTECTED]:~$ xhost local:root
non-network local connections being added to access control list
[EMAIL PROTECTED]:~$
[EMAIL PROTECTED]:~$ xhost
access control enabled, only authorized clients can connect
LOCAL:
[EMAIL PROTECTED]:~$
[EMAIL PROTECTED]:~$
This appears to allow any user on my machine to access my x server. Is 
there a way to restrict it to root only ?
