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)

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.

I'll have a look.
Thanks *very* much for the info,
