I'm positive you're already familiar with all this, but just 
for the archives:

Inclusive trees eliminate the need for too much state in the 
core, but requires that all Receiver PE routers are aware 
about the Multicast infrastructure regardless of whether 
they have downstream listeners or not.

Selective trees are the exact opposite. You can choose which 
Receiver PE routers will handle Multicast information so 
only interested receivers attract traffic to the right 
Receiver PE routers, but it increases the amount of state in 
the core.

I would really like to see how mLDP plays into this whole 
mix.

Cheers,

Mark.
