AutoIp is Link-Local Addressing per RFC3927. I am not sure it is fully
compliant and I am pretty sure its interaction with DHCP is *not* compliant.
I suppose a bug-report should be filed to verify why I think it isn't
compliant with DHCP and to resolve it if it isn't.
ZeroConf is a standard and well-defined. (Interestingly the IETF didn't see
it as very important and there is no RFC on it and a workgroup for it has
gone missing). Most commercial devices do support it (like printers, etc.)
as does Windows, Linux, and Mac-OS. It was the basis for Apple-Talk and
grew into Rendezvous and now Bonjour. Link-Local Addressing is one of three
components of ZeroConf. I wouldn't call AutoIP "limited zeroconf". It's
Link Local addressing and well defined. It might be nice to have Zeroconf
support since it makes listing and accessing devices easier while following
a standard.
