OK, as explained to me in the context of X.org, customers, etc;

xinerama is an X extension allowing a server to create a single virtual
screen from multiple framebuffers.  That virtual screen tiles the
physical framebuffers into an M x N array which is *transparent to
apps*, and which was used to create "one big display" from smaller
framebuffers.  Primary use case was "wall of monitors", i.e. monitors
arranged in rows/columns.  This was Xinerama as implemented in XSun
before it had any existance in XFree86, as I understand it.

The customer expectations were (for our purposes anyhow) very clearly on
the side of the "one tiled display" interpretation.  

Obviously it makes a difference who you are argui^H^H^H^H^Hasking; other
people think it's "obviously" supposed to be a multiscreen-for-dummies
or something.
