If you don't pass the -rfbauth to Xvnc you don't have to authenticate.

Except the -rfbauth is already passed by default in the vncserver script. 
And having a blank vncpasswd file is not the same as not passing -rfbauth
at all.

WORKSFORME.  I just tried it with both the Linux v3.3.7 and v4 beta4
viewers against a Linux v3.3.7 Xvnc.

Definitely don't take this as a flame, just a point to ponder.  Will you
remember how these four computers are set up if you get Internet access to
one of them?  How about if you add a wireless access-point?
