Rich, No, you are not missing anything - NBMA without neighbor statements over serial links SHOULD not work and in most cases, won't.
Welcome to my world! Chances are that you experiencing "EpisodeOSPF the Phantom neighbor" I have fought this for over 6 months while studying. The dead interval keeps renewing and the neighbors SEEM to be up, but, if you clear the OSPF process or reload the routers, the connections should die - even before you reload the routers the routes should have been unreachable - EXCEPT in the case of another connection between the routers. Another OSPF goodie! If you have an ehternet or other broadcast connection, as well as the NBMA serial link the little hellos for the NBMA connections piggyback on the broadcast connection and bring up the neighbors anyway (even if in different areas! and a traceroute will show a direct connection!)in this case the neighbors remain after clearing or reloading and are reachable. (This behavior is probably not OEM design) Just two of many OSPF quirks! You have the concept! keep your eye on the prize!
