  I suspect you will need internal changes: Multics Emacs does it
easily because there's architectural support for it in the
hardware and operating system, so all you have to have is the (usual)
have-i-two-windows-on-this-buffer update checks...
  You may need a private communications path between the emacses on
Suns, stating what each have changed where they overlap (somewhere
close to the minimize-screen-redraw code).  This is also reminiscent
of the "parallel two databases by transmitting each other their
journals" trick.
