xinerama between 2 vnc (seamless desktop)

[j.mrazek]

Hi,
  does anybody know howto create seamless desktop
from two vncs (move windows from 1 vnc to the other)? 

I searched a lot, no result.  Nothing like vnc2vnc found,  
x2vnc  works afaik just from real to virtual and anyway 
it does not transport windows - just mouse and keyboard.

 My case 1:

a/laptop - 1024x768
b/big screen 1280x1024
c/remote pc that runs my (X) programs (in vnc or several vncs).

    I have an application that runs and displays on remote
pc and I check the results and work there via vnc. So far so good.
The problem arises when I want to connect from smaller or bigger display
then Xvnc has. Ok - use paid version of realvnc - you answer. 
(they offer desktop scaling). Hmmm.

My case 2:

  I would like to have a seamless desktop (moving windows) through
multiple monitors on multiple machines. There exist a solution -
I can run a special xserver, but using vnc would be *extremely easily*
scalable. You just open whatever you want wherever you want.

thanks,
