     Dude!  I'm a moron!  That's exactly it.  I forgot to specify the other 
     machine with xhost!  I can't believe I'm even admitting to this!  
     Let's just say I was asking for a friend, OK?
     I'll take a look at the xauth too.  That may be more where I'm trying 
     to go.  Thanks alot.

Yep, that's an xauth issue.  Easiest way around this is to do a 
  xhost +  # disables X authentication completely 
  xhost +host.connecting.from
Note: You run this command on the machine you want the X session to 
display ON, not the machine where you are running the client.
BUT, if you need this machine to be secure, this is probably NOT what you 
want.  In that case, take a look at 
  man xauth
It's much more complicated than xhost (and much more complicated than it 
needs to be, if you ask me...) but it's also a whole lot more secure.  I 
never use it, because I'm too damn lazy, and because I now use ssh which 
does an end run around the whole issue by taking care of the xauth stuff 
for you. :)
And, BTW, ssh ROCKS!
