I can see your point. If Avahi returned the 192.168.x.x IPs for the
cameras,
I'd be running into that problem. So the right way for Avahi to do
this is,
as you say, to use the 169.254.x.x addresses...
(I now wonder if windoze's uPnP can handle two cameras with the same
192.168.x.x IP... I guess not)
Nope, IP networking in general can't handle two machines with the
same IP address.

about this
address range.
Yes; I now have a IP alias (eth0:0) with a 169.254.x.x address.
However, the default network configuration for most Linux boxes is
to have
just one IP, and not be aware of the 169.254.0.0 network. I guess
that making
Avahi aware of the routing table to decide whether to get the
169.154.x.x or
the 192.168.x.x IP would be a real mess.
Right, you don't need to configure an additional IP address on your
box. You just need to add a routing table entry indicating that
169.254 addresses are local.
