I agree that it's not really Windows-specific, since any OS could
implement the protocol. I guess I've only encountered it on Windows, not
being a Mac user. I don't believe that it's what a DHCP client is
"supposed" to do, though, as it's outside of the DHCP protocol. I don't
find any mention of it in the DHCP RFC (2131). The Internet draft I
quoted earlier is basically an add-on to DHCP.

I've certainly never seen my Linux system do it (Slackware 10), but it
does seem to be available on other distros. Maybe Slackware's just
behind the times.
Personally, I prefer not having it. I can see its utility if I wanted to
run a workgroup of computers that only communicated with each other, but
as soon as a gateway to the internet enters the picture, something mroe
is needed. I've only ever used the 169.254... address as an indication
that my router is down. Okay... I admit I did use it once to do a
crossover link between two laptops (it saved me assigning some static IPs).
