Nope. All quake servers are manually configured (though fteqw is based on Quakeworld's network code and protocols which has some prediction in it) though recent darkplaces releases have reduced some of the lag too Take your pick (yes, fteqw servers require fteqw clients to join, same goes for darkplaces)
ok, bearkub did an excellent job of getting the pain-in-the-ass coop mode working, meet roughly 8pm gmt at nibbler.fastpc.com if your up for some quakeing! edit: using darkplaces engine!
