Hi, 

Because RPL is a Route-Over routing protocol, it is applicable to many different L1/L2, including the well-known 802.14.5 and their last improvements/updates, PLC  and many others ...

Thus, I think we should avoid to bind RPL to some specifics L1/L2, or we would need to update RPL for each new L1/L2 created that aim to use RPL.

Cédric.
