[NTLUG:Discuss] Auto Login?

[lee@brave.com]

Right now I've got the standard console login after bootup, and I was
thinking of using xdm for that fancy graphical login... but that got me
thinking about something.

How would one go about setting up the login sequence to go straight to X /
desktop for a user?  That's right, no password or anything; just turn on
the machine and have it go straight to the desktop after the boot
sequence.  (kinda like that other "popular" OS ;)

As far as network security goes, the machine is masqueraded behind my
"server" on a cable connection.  No one should have access to the computer
remotely unless the server has been compromised, right?

And for physical security, no one uses this computer but me and doesn't
have any other user accounts on it.

So what do ya think?  Possible?  Foolish?  Any drawbacks I'm overlooking?  
If it's possible and not a st00pid idea, I'd like to know how to do it.

Thanks,
