Good call, IMHO. :)

The most popular use for multiple X servers per X client used be as an
lazy-programmer (and insecure, bandwidth-expensive) way to write
multiplayer LAN games for Unix workstations.  Recent era, network
multiplayer games have moved to more sensible client-server models.

If your goal is to do "shared whiteboard" tutorials of MrEd apps like
DrScheme, I'd try something like XMX
("http://www.cs.brown.edu/software/xmx/") or a multiple-display hack
based on VNC or RDesktop.

If you wanted to share non-GUI MzScheme app displays, you could use GNU
Emacs.  (At least one of the wearable computing people has done this for
demoing what he sees on his head-up display.)
