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.
