Thank you for mentioning my proposal.  I believe that the two approaches are 
complimentary.

While my proposal attempts to provide a more universal solution to the problem, 
it requires a BGP update and an implementation by all routers on path between 
the initial advertiser and the router performing uRPF.  This draft proposes a 
solution that can immediately work w/o a change to BGP on the router that 
implements it, albeit in a more limited set of circumstances.

Therefore, I support the adoption, and I am interested in more discussion in 
this problem area.
