Hi Toerless,

I would *love* the DSL community to take an interest in DLEP (from a purely personal perspective it could help make my home connection more stable, using a selection of the techniques you describe) but I'm not sure what the next step is.  I know there is an IETF/Broadband Alliance liaison, but I think it's mostly centred around YANG model alignment, and I'm not even sure the Broadband Alliance are the right SDO.

Anyone have any suggestions?

Rick
