[multrans] Section 4.5. "Combination of ASM and SSM Modes" in the Problem Statement

[Tom Taylor <[e-mail]>]

Section 4.5 is really talking about multicast sub-tree optimization, 
achieved by taking advantage of the fact that there are multiple 
sources, each with its own tree to start with. ASM is just a speculative 
approach to the method of achieving this. It's not full ASM anyway, 
since there is no intention to treat the IPv4 sources as receivers.

I assume that the optimization criterion is to reduce the aggregate 
capacity required to carry the flows through the IPv6 network. I don't 
know whether the intended algorithm is meant to operate dynamically each 
time a receiver requests a multicast stream, or is meant to operate 
offline given the stable positions of the sources, at least. In any 
event, this sounds like an interesting research project, but I don't 
think it's a suitable topic for the Problem Statement.

My vote is to drop the section.
