Experiences with X in a wireless environment

Wireless computing is all the rage; the X Window System seems to be inescapable. We have been experimenting with the cross-product, and have had mixed results. The network may not be the computer any more, but it certainly influences the way the computer performs, and adding a fairly atypical network layer cannot help but expose some underlying assumptions. We discuss a few that we found and go on to speculate about how to best push X in the direction of mobile and location-independent computing.
