Nova does use RPC for resizes and migrations.

The SSH keys are for tranferring the instance image data, which would be
inappropriate for RPC.

I think Nova would be open to other means of bulk data transfer if
someone comes up with a reasonable proposal.

I think rsync over ssh was chosen since it's common enough to be
familiar to most people.
