Hi George,
Have you considered using Avahi/Zeroconf/Bonjour to look up your hosts?
This usually will result in wired interfaces being used before wireless,
and takes care of changing IP addresses for you.
Use $Conf{ClientNameAlias} = 'hostname.local' for each host. On most Linux
desktops and Macs, this will just work. On Windows you may need to install
the Bonjour client.
However, I imagine you'll still have issues with the DNS hijacking if the
host simply isn't online.
Regards,
Tyler
