If I wanted a realm for RAEBURN.ORG, I might set up one of the
machines at Cygnus as the primary server. The two most likely
candidates are both running slave servers for CYGNUS.COM.

Will that handle principals being deleted in the realm for which the
server is a slave (i.e., an entry in the database for which there is
no update in the dump file because it is supposed to go away)?

Sounds like another reason for keeping the databases (and all
associated data) separate.
