Actually, I can believe that the multiple font support, et al. would take some space. It shouldn't take too much effort to support a text-only version that'd bring up an alert panel. > > Now, why can we simply write a 10 line program that uses NXRunAlertPanel > to run a alert-panel with an OK button, and then arrange to have it run > remotely on whatever machine you wish it run on...

For zephyr at CMU (from /etc/services): zephyr-clt 2103/udp zephyr-hm 2104/udp So the answer is yes. At CMU, the user has to start up his own zephyr daemon, but it could be done from /etc/inetd.conf as well. If I have a large amount of free time, I'll look into whether I can tackle the problem. -Chuck +---------------------------------------------+ | Charles William Swiger -- CMU sucks rocks | "The television screen is the | AMS & normal mail: cs4w+@andrew.cmu.edu | retina of the mind's eye." | NeXTmail: <temporarily out of order> | +---------------------------------------------+ --Videodrome
