We discussed that last time, and I think it was Roger who proposed a patch to ifconfig so that it would send an ARP request first and complain if the IP you're trying to set is already used.
We're left with the question as to whether ifconfig should by default complain but put the IP anyway, or refuse to put the IP unless you give it some --ignore-IP-conflict flag. That approach is not incompatible with the kernel patch, and I believe that both should be implemented.
