1. Tunnelling over the very same protocol; e.g., IP-over-IP


I think there are operational reasons why might want to do this.
Building an architecture based on this is probably flawed though.


IP-over-IP may be a confusing way to say what you get, which is more like:
    "IP++ over IP"

IP++ gives you more than the base IP:

    - topology abstraction
    - isolating a set of addresses or services
    - emulation

I.e., VMware will be complete only when we can run VMware inside a
VMware partition. The same is true for networks, which is why IP- over-IP
is the most meaningful virtualization of all, IMO.

Yes, but those are operational reasons. Not architectural. At least to me.
