I think it is early to say. Cloud networks have been all Layer 2 based and because of that many mobility issues do not surface. For example virtual machine mobility is just change of Ethernet address and no IP layer changes are needed. However, I think that the trend is towards Layer 3 based clouds and also inter-cloud communication needs are increasing. For example there are many people advocating the development of an IETF virtual machine mobility protocol. I think we need to look at DMM from this perspective,and see if we can make our mobility protocols more suitable to the cloud. That is the reason why I wrote draft-sarikaya-dmm-cloud-mm. With even the simplistic assumptions, my drafts shows that the cloud does have some protocol implications on our protocols.
