There's no easy way to retrieve the Computer Name of the service, but 
starting in Tiger, you'll be able to get the hostname after resolving 
the service by using the new NSNetService "hostName" method.  If you 
need to get the hostname in Panther, then you'll need to use 
DNSServiceResolve() located in /usr/include/dns_sd.h.
