Since xend configuration files are just python scripts, you could add 
something to the config files.

There are a few VNC terminal programs--none are very good (including my 
own).  I've been exploring this area quite a bit.  This is a tough area 
b/c it takes a lot of work to be a full terminal emulator.
An interesting approach would be to use vncserver to create a VNC 
session with the resolution of an xterm and setup the vncrc file to only 
start an X term positioned at 0, 0.  If you don't start a window 
manager, and change the background/foreground color, it should give you 
what you're looking for.
