I think the MT will provide the network virtualization which is based on the basic topo of the forwarding device.
It should belong to either orchestration or application (SDN point of view). OF controller should only support OF, no more intelligence such as decision for routing and switching.
I don't know if IRS frame work should cover this since IRS frame work has a lot debatable areas.

This morning Scott mentioned that he would like to use IRS to shut down 
all protocols and just be able to write to RIB. Now James said that he 
would like to get a network topology as "every OpenFlow controller 
requires this"

Both connected together resulted in an idea of using 
multi-topology-routing where your base topology discovers physical link 
connectivity graph while other topologies could be programmed by 
external entities example: OF controllers or any other external to 
routers network intelligence oracles to deliver actual services ?

Would that be in scope of IRS effort ? If so what would be the proposed 
"write to RIB" set of protocols ? Would you support OF 1.3 even if one 
would be happy to lock such topologies only to software/programmable 
switching paths ?
