What problem are we trying to solve?
I think the original idea was to make Bonjour aware machines work
together even in the absence of a routable address. But after
I took a look at the RFC, I guess I'd better ask the above question
before further investigation.
Multicast service discovery is what makes IPv4 link-local addresses
useful in ad-hoc networks (assuming applications know about
one-another's services).
With MacOS, for example, it's very easy to share iTunes music libraries
between two laptops that are otherwise not part of a publicly addressed
network. It's almost as easy to do the same with iTunes between a
Windows machine and a MacOS machine. If such applications existed on
Solaris, IPv4 link-local addresses would automatically have a use.
Otherwise, their use is limited to network trouble shooting (IMO).
