a) I would hope that a discussion of what will work great for I2RS would 
occur on the I2RS list.

b) Rather than "it runs in with this controller", I would really like to 
see an analysis (for it and the other choices) of how the proposal 
actually stacks up against the WG requirements.   While the fact that it 
runs is important, the current ODL (or other running SDN environments) 
simply do not stress many of the stated requirements.

c) Note that the above is as far as I can tell orthogonal to the 
question of how we will configure NFV virtual servers or service chain 
forwarding.

Yours,
Joel
