Yoshi, I think you're focusing too much on the benefits of this solution and not considering the cost. We've seen time and time again that when middleboxes get involved in transport layer operations they break the end to end nature of TCP and that leads to problems. Middlebox involvement in TCP is one of the major source of protocol ossification on the Internet. MPTCP is just one feature of TCP that we might want do deploy there are many others. If this solution hampers use and deployment of those, then I don't believe this is a reasonable tradeoff regardless of what the benefits are. Tom
