1) The Avahi's compatibility layer doesn't implement the now deprecated
function DNSServiceRegistrationCreate().

2) Unless DNSServiceRegistrationCreate() installs a lot of black magic,
the Bonjour code in postmaster.c has very poor error handling: There
seem to be no attempts made to handle name collisions (unless Bonjour
does this automatically, of course).

Ciao,
