Instead, the X +server must move to a model where it is told +what to do by external agents, and do so in a +dynamic fashion, in response to a user's +action. + +Additonally, projectors and other large +displays, calling out to be used by more than +one person at a time, are becoming +econonomical. Input devices themselves must be +able to be network devices, and the X server +become a multi-user server, if this vision is +to become a reality. + +The issues faced break down into the following +categories: +\begin{itemize} + \item fundamental X architectural issues + \item XInput extension protocol issues + \item Integration with the desktop environment + \item X server implementation infrastructure issues + \item Security and authentication + \item Device discovery, authentication and association +\end{itemize} + +Hotplug of display screens present similar +challenges, but such hardware is either rare +(PCMCIA/CARDBUS displays) or not yet widely +deployed (e.g.\ PCI-e), it is out of the scope +of this paper. + |
