..check out sdm and sdm-terminal, if you wanna provide X logins over
ssh, the user sees a menu to choose from and you should be able to 
"pile up the good boxes" on top of that menu listing:
arnt@a45:~ $ apt-cache search sdm
bsdmainutils - collection of more utilities from FreeBSD
bsdutils - Basic utilities from 4.4BSD-Lite
cfv - versatile file checksum creator and verifier
sdm - Secure Display Manager - secure remote access to X11
sdm-terminal - Secure Display Manager - terminal files
turqstat - Fidonet and Usenet statistics program
xturqstat - Fidonet and Usenet statistics program for X

Description: Secure Display Manager - secure remote access to X11
 sdm is an X11 display manager similar to xdm, gdm and kdm, but unlike
 those it wraps the X11 traffic within an ssh tunnel to provide a secure
 login mechanism for remote X sessions.
 sdm provides access only through SSH, not locally. It is technically
 possible to access an sdm server from same host, but probably a waste
of CPU power.
 .
 This package should be installed on any server acting as SDM server.
