I agree that non-storing mode addresses the primary AMI use-case where endpoints push data up and through the DODAG root.

Could there be a "hybrid-storing" mode that doesn't use as much RAM to contain routes to all nodes in a sub-tree? Instead of traditional storing mode, could a node store just multicast memberships in all nodes "below" a particular mote ?  Assuming there would much fewer multicast memberships than would be required for RFC 6550 storing mode ?  It's a variant of storing+multicast, without the traditional storing mode RAM usage.

I'm still looking at the MPL document, so apologies if that's already discussed.

Ah, I did not understand that from your previous email.
Yes, please.  Pick non-storing, and lets' proceed!!!
