you at local$ xhost +remote
you at local$ ssh you at remote
you at remote$ export DISPLAY=local:0
you at remote$ xterm&
you at remote$ exit
you at local$ xhost -remote

<disclaimer>I know this is the most insecure method of allowing access, but
for now it works.</disclaimer>

alternatively, you can learn about MIT_MAGIC_COOKIES
or, as you mentioned, you can use ssh.

ssh -X -n you at remote /usr/X11R6/bin/xterm

I'm not sure you need all of these switches, but this works for me through a
firewall to my home box from work.

NOTE: ssh will be much slower and if you are on your own LAN, secluded from
the world, it is unnecessary.

Here is my $HOME/.ssh/config
it helps with using X over a slow connection.

Compression yes
ForwardX11 yes


always RTFM! It's all there (if you know how to filter for what you need.)
