where to put xhosts commands

[Paul Lemmons]

I need to allow several machines to use the x server on my machine. I 
have altered kdm.conf and now if I run "xhost +" I can run x 
applications from another server. I would like to be a little more 
granular that "xhost +" and I don't want to have to type in the commands 
every time. On my Fedora box I set up a script in xinit.d. No such 
directory exists on Kubuntu. Where would one put a series of xhost 
commands so that I can set it up once for all users and forget it? Is 
there a better way than xhost?
