Hi Toerless,

Thanks for the interesting post!
I'm glad to see that our ICNP paper was cited in the draft. Actually, we have published a more confined draft focusing on the IoT/edge network scenarios where shorter addresses is preferred for the sake of overhead and power. 
https://datatracker.ietf.org/doc/draft-song-ship-edge/
It works in a limited domain, but interoperable with the public Internet. I think it could be a solid starting point to explore more potentials.

Cheers,
Haoyu

Dear Int-area

As attached below, i have written up an idea about why and how variable-length addresses in the network layer would be useful for many limited domain internetworks, but also how they could provide a simple and easily extensible framework to add additional semantics (the likes of multicast, BIER, ICN), and also make it easier to express the programmability that SRv6 introduced.

Would very much welcome discussion/feedback, and will be asking for a slot to present/discuss this int-area 111.

Note that the -00 writeup is mostly inspirational for what i think the cool things one could do with it are and to explain the concepts.

Obviously, if/when there is interest in this direction, the harder work of figuring out how to best introduce this incrementally, and ideally backward compatible into existing networks wold be the next big set of items to work out.

Cheers
    Toerless
