Shared logins?  Makes no sense to me.
Where is the security in that.



Anyway, since you brought up dealing with different monitor sizes
here's how I deal with rxvt on different terminal sizes using
xrdb and X-resources:

#if ( HEIGHT == 900 )     /* Traditional Sparc */
Rxvt.geometry: 80x55
#elif ( HEIGHT == 1024 )  /* Sparc 21 inch */
Rxvt.geometry: 80x65
#elif ( HEIGHT == 768 )   /* Exceed in 1024x768 mode */
Rxvt.geometry: 80x47
#else                     /* I have no idea... */
Rxvt.geometry: 80x40
#endif

The man page reveals other values you can access besides HEIGHT.

Another person mentioned running xrdb and reading an .Xdefaults file.
A common problem with .Xdefaults is that it can rapidly accumulate
huge amounts of junk.

Here's how I deal with that in my .xinitrc:

  cat $HOME/xdef/*.ad | xrdb -load

The xdef directory contains:

Emacs.ad
exmh.ad
xterm.ad
etc.

Makes it easy to remove things you no longer use.
