Hmm, learning something new like most days:
sample/example cli?
Something like 

export DISPLAY 192.168.xx.9:10:0

 on the pi, and

xauth +raspi on the odroid?

I have the X manpage up on the odroid and I am logged into the pi too.
From that manpage I should set and export DISPLAY to
 
  hostname:displaynumber.screennumber, so on the pi

setenv DISPLAY odroid:12.0
or
DISPLAY = odroid:12.0
export DISPLAY

on the odroid64
xauth +raspi

then to conserve keyboards, log into raspi, and start my x using program

Have I got it right?

The reason for the 12 is that as I am logged into the odroid twice right 
now, so screens 10 and 11 are already in use with my ssh -Y logins and I 
asumme I can't re-use a display number.  Or should I re-use the display 
number, and enum the screen number some how?  Obviously this is 
something I've never done before. I would also assume the ssh login 
would be without any -X or -Y options. 

So Plz clarify.  If this gets rid of most or all of the lag, I'll be in 
hog heaven.

Thanks Peter.
