I did this just one time:

   server/bin/bb localhost "status server,domain,com.bogus green `date`"

server.domain.com has never have existed in my bb-hosts file.  It showed up
in the Ghost Clients web page for 5 minutes.  It also showed up in the
ghostlist generated via this command:

   server/bin/bb localhost ghostlist

Several days later, the above command was still showing this:

      server.domain.com|127.0.0.1|1211218983

This was with the Jan 25 2008 4.3.0 snapshot.
