I don't really know anything about /etc/hosts.allow, but to run X clients
from another machine I do 
xhost +machine.name
And then you can run the clients from there. An alternative which is very
convinient is ssh, which automatically redirects X connections, so if I do 
ssh -f pseudo.ml.org netscape -geometry 500x450
ssh makes a pseudo screen on pseudo:10.0 which redirects things over to my
machine. ssh is also a good thing in general.
