The only NBP wildcard for zone names is *, which matches the *current*
zone.  Thank goodness there's no "all zones" wildcard -- such an
internet-wide broadcast would melt down nets like ours (82 AppleTalk
zones and counting).

The only way to look for an entity in all zones is to use ZIP to get a
list of zones (the code was included in Tim's message) and do one NBP
lookup for each zone.  So it's hard, as it should be.
