Avahi allows the workstation running it to advertise and solicit mDNS
information.

OK, I should have said a rival to ARP + dhcp.
But it's not; ARP+dhcp is all about mapping MAC-IP. mDNS is dealing
with name-IP.
mDNS competes with _DNS_; it's a way of doing local DNS without needing
a DNS server.
As I see it,

Isn't that more or less what I said above?
It's almost the opposite. mDNS does name-IP and let's people
find other machines; DHCP does MAC-IP and let's a machine find _itself_.
Or, another way of looking at it.

Is it only used within local LANs?
