avahi-core is intended to be used in cases where you just want to have
a single process that implements an mDNS stack and thus want to embed
it. It is not recommended to run more than one mDNS stack on the same
host. Instead you should then simply share a single mDNS stack
instance by multiple process, possibly by simply using the
avahi-daemon we ship via D-Bus.
