One caveat here: some Linux systems have port 6000 disabled by default.  
If you're used to running X apps in "the usual way", you'll go nuts 
wondering why nothing (including xhost) works.

I ran into this with SuSE 9.1.  It's a Good Thing from a security 
perspective but if you want to disable it and return to a normal life, 
check your release notes.  (In SuSE, the relevant line is in 
/etc/sysconfig/displaymanager, as I recall.)
