Section 2.1: Applications such as real-time multimedia streaming may not be able to tolerate such increase in packet delay. I wouldn't clasify streaming as a particular delay sensitive application. An increased network delay does only add to the intial buffering for such applications. However when talking about real-time communications in general the delay is certainly an issue.

There is a lot of good work here. The solutions document provides an excellent survey of the existing work. But the analysis seems lacking especially in areas where the existing work is kind of lacking, such as security. I don't believe that this ballot is sufficient as a basis for a standards-track nemo ro approach. There are a lot of discussions of security, architecture and how well considered the input proposals are that still need to happen. I think there needs to be significannt input from the IPV6 and MIP6 communities before we get to an approach that is likely to withstand IETF review. I'm balloting an abstain rather than a no-ob because it seems like there is a lot of half-baked analysis mixed in with some really good stuff and I'm concerned that separating it out will be hard. Specific examples that really triggered this abstain include: The claim in 2.5 of the problem statement that there is a security problem associated with accepting traffic from visiting nodes. The idea of using an anycast address to find correspondant routers. The idea of creating a multilink subnet for all the nodes in the mobile network. Use of CGA to prove ownership of a prefix. Yes, these ideas have been brought forward. They should be discussed. But the analysis seems rather incomplete.
