I also argue that what they are asking for really is in conflict of the purpose of a cloud
environment. If you are merely after a virtualized environment you can use vsphere, kvm with
virt-manager or xenserver. Multiple IPs per nic do nothing to improve the performance or the
functionality of a cloud environment.

Going down the road of adding features like that would be taking valuable development time
away from tasks and features that actually benefit a cloud architecture. While I do understand
their issue, there are other ways of implementing what they are listing as reasons that is
cloud architecture friendly. (using NAT and isolated private networks for one)

I am conflicted on this - I know the limitations with adding
additional interfaces. I'd almost argue for requiring number of
interfaces/IPs to be set at machine instantiation and still handing
out addresses to all interfaces via DHCP, but not all OSes will handle
that cleanly.
