XMX is a standalone utility for sharing an X Window System session
on multiple X displays. It allows users to see and interact with the same
applications at the same time from different locations. XMX takes advantage of
the networked nature of the X Window System by acting as an intermediary between
X clients and X servers. In this way, XMX works with any X clients and any X
servers, without the need to modify either.
XMX provides a WYSIWIS (What You See Is What I See) environment; it paints the same graphics on
all participating displays. The shared client applications appear to each
participant in a virtual root window which is subject to local window
management. In this way, the shared X session coexists with each user's private
X session.
The X client applications which are shared via XMX are unaware that they are
being viewed or controlled by more than one user. Existing, single-user X client
applications may be shared using XMX without recompilation, relinking or access
to source code.
XMX is designed as an application sharing server. It provides both the
mechanism of application sharing and a way to control the shared session from
other programs. Like X, it leaves policy decisions to application programs. In
this way, XMX may be used as a component in any of a variety of systems that
require application sharing.
