Using ssh to run a program on a remote computer

[Rick Bilonick <rab nauticom net>]

I need to start camstream from an ssh session on my computer at work. 
This allows me to change the settings through its X11 gui. (This is not 
entirely convenient because it is very slow over a dial up line, but it 
works - just barely.) The problem is, I want to then restart camstream 
on the remote computer (at home) but have the display show up on the 
remote computer (at home, not the computer at work I'm connecting from). 
I tried running

> ssh -x -l me xx.xx.xx.xx

but I get an error. Here is what happens if I try to run xclock using 
"ssh -x ...":
