if you are using novas api to manage floating ips then you might be able to lock the instnace which should prevent changing
the ip assocations and most other instnace actions however if you were to manage teh floating ips form neutron that ouls entirly bypass that.
we had talk about adding the ablity to lock ports for a different usecasue and haing nova lock the port whenever an instance is locked
that might be the way to adress this in the future but for now i dont think you can do this without custom midelware.
