His review:

Summary: No objection

This draft suggests an optimization for multicast through
L2TP tunnels, such that the same flow will not be sent more
than once between the same two L2TP end-points. This is a
Good Thing if it can be achieved - it doesn't however
guarantee a logical multicast topology (any more than the
MBONE does). It is quite complex and adds some administrative
configuration tasks. Experimental seems appropriate, since it
isn't clear whether this will prove deployable at a large
scale.

The draft is quite well written, but I did notice one nit:

> 4.2.     Group state determination        Source Filtering Group 
> Management Protocols require querier routers...

"querier" doesn't seem like an English word to me. Logically,
it should be, but I don't think it is. It certainly isn't
an adjective.
