You can see DPP in the context of the EasyMesh efforts - not in regards to USP.
While mesh topologies are also getting covered by USP I think that DPP is
not a topic, yet.

From what I can see in the projects the major use case for USP (TR-369) will be 
replacing TR-069 for managing the gateways. But so far the large carriers do not 
seem to have a migration strategy, yet. Since both transports (TR-369 & TR-069)
use the same underlying data model (TR-181) that’s technically not a huge step.

I think organizing a Hackathon or similar might be an approach, what do you
think?

I think you’re right, there are a lot of announcements but what really happens
needs to be seen…

Thanks!
