Remember that when you register a NBP name on the net using NBPRegister 
(IM II-299), it checks the network to make sure that the particular 
name:type@zone NBP tuple isn't registered somwhere else in some other 
note, and lets you know if it is.  Thus, if you managed to register the 
name successfully, you can be (reasonably) confident that your name is 
unique.  This is assuming that you are following the AppleTalk convention 
of using the user name entered in the Chooser as the "name", and an 
identifier unique to your application as the "type".
