It has been a long time known fact that a jail with 
xorg/what-ever-desktop does not work when trying to login to that jail 
from the host. Reason is xorg uses kernel to access syscons and the jail 
don't allow it that access just like its suppose to do. Now remotely ssh 
into that xorg jail works.

So the question is when newcoms is on the host and the jail has 
xorg/what-ever-desktop installed can a host user login to that jail and 
have xorg/desktop work on the hosts screen? Host user means someone 
setting at the host computer console video device. Login means execute 
"jexec jailname tcsh" to open console to that jail.
