I had thought about that as a possibility. My thought was if I created like a /dev/ether0 and then symlink'ed it to /dev/fxp0, in the event of a failure, I could just change the link over to fxp1 and my firewall rules, dhcpd configurations, et al would still work since they were just reference the symlink (assuming I can do something oddball like that). I was just hoping that someone with more skill than I had put together a more fluid means of all this happening..
