I reviewed this draft on behalf of the OPS directorate for operational considerations. 

I think this draft is largely ready to go. Toerless had some comments during last call against draft-07 which are worthy of inclusion. In particular, The distinction between BSR (rfc 5059) although pointed out in the introduction is important enough that it should be captured in the title.

From my general understanding of the mechanism  there are  probably limitations to how well ti apprach scales which limits it's applicability to large pim domains. The experimental status is therefore quite appropriate. It represents significant improvement over dense mode pim so in the sense that it offers the opportunity for significantly lower coordination/signaling requirements without the destructive nature of flooding and then pruning the source traffic. it is quite appropriate to proceed to experimental status. When we move on from that I would be willing to bet that applicability will need to be refined accordingly.
