With the automounter (man 8 automount), you can set up, say, copies of the man pages on three different servers and have the automounter pick up one of them on demand, insulating you from both dead servers and providing you with load balancing. As for whether particular vendors support it, Sun's ONC/NFS Technology Guide (ask your Sun rep) has a chart that shows about 30 automounter implementations, including DEC Ultrix.
