Open Stack

I think this work falls into the "service VM" category.

openwrt unlike other service VMs used for networking services (like
cloudstack's router vm) is very lightweight, and it's fairly easy to
provision such VMs on the fly. It should be easy also to integrate with a
ML2 control plane or even with other plugins.

It is a decent alternative to the l3 agent. Possibly to the dhcp agent as
well. As I see this as an alternative to part of the "reference" control
plane, I expect it to provide its own metadata proxy. The only change in
neutron would be some sort of configurability in the metadata proxy
launcher (assuming you do not provide DHCP as well via openwrt, in which
case the problem would not exist, probably).

It's not my call about whether this should live in neutron or not. My vote
is not - simply because I believe that neutron is not a control plane, and
everything that is control plane or integration with it should live outside
of neutron, including our agents.

On the other hand, I don't really see what the 'aaS' part of this. You're
not exposing anything "as a service" specific to openwrt, are you?
