Being optimistic I published a refresh of the draft tough we did not get a lot of discussion so far. https://www.ietf.org/id/draft-thubert-roll-dao-projection-01.txt
The new version adds the capability by the PCE to add routes in a RPL network. This may be useful for 6TiSCH when the PCE does not install tracks but simply adds IPv6 routes for which OTF/6top will adapt the bandwidth.

So in preparation of Yokohama, I'd like to sense interest in that topic. Continue, or drop? Please jump in! Pascal
