Roger that. :-)

Yes, I know this isn't the way the protocol says how to do it, but this is the way
I need it to be done... Since I'm thinking wireless, I want to preregister an address on the subnet the mobile terminal will roam to and use that address when I decide to associate with that access point. After that I can release my old address. Everything to minimize (hopefully
eliminate) the packet loss. 
So I want the server to allow selective release, check if that address is kept by the host making
the release and if that's the case, release it. OK?
