You also need to mess with /etc/ssh/sshd_config on the host side. Then run
your program and it will be sent to your local computer. The sshd one needs
2 changes, X11 Forwading and XAgent (or something like that) and they
should be right next to each other. I recently setup this on my home
computer so I could edit my data in gnucash from the office. It's pretty
cool, but the program is a little slow in response. xclock is a good
program to use for testing cause it's small and will respond quickly.

I was confused at first thinking I need a parameter on the remote host like
-display localhost:0.0 or something, but that isn't true. Run it just like
you would normally.

I haven't messed with the public keys yet, maybe I should though. I'm
comfortable with passwords because I don't see myself as a high-level
target.
