[j-nsp] The P2MP LSP story when using LDP for VPLS?

[Clarke Morledge]

I am in the process of building a VPLS implementation using LDP to build 
the LSPs but using BGP to handle the L2 signaling:

I know that there is a dynamic way to configure point-to-multipoint (P2MP) 
LSPs when using RSVP with the "provider-tunnel" keyword for each VPLS 
routing instance , but I don't quite understand how to do this with LDP. 
I'm getting a little lost when reading this:

http://jnpr.net/techpubs/en_US/junos10.0/information-products/topic-collections/feature-guide/vpls-traffic-flooding-p2mp-lsp-solutions.html

I see that there is some IETF draft work being done on P2MP for LDP:

http://tools.ietf.org/html/draft-ietf-mpls-ldp-p2mp-08

Does this mean that dynamic P2MP LSPs for LDP with VPLS isn't available 
yet, or is there some other workaround?

I'm having some difficulty trying to wrap my head around this.  The 
ultimate purpose is to cut down on unnecessary packet replication due to 
broadcast, multicast, and unknown unicast within VPLS.  I would rather not 
use RSVP since it is more complex to configure than LDP, but perhaps LDP 
isn't ready for P2MP for primetime?
