I think this is a proposal that should be discussed separately - for instance it needs INT-area expertise. I think the proxy-work is built of two items: 1. The documentation of how a deployment of one-ended and two-ended proxies look a like and the things that one should consider when doing so. 2. The plain-mode-option. The point 1) is specific to MPTCP and probably useful to include in the charter. For the point 2), I agree with Alan's comment in that this is entirely independent from MPTCP. It is basically a mechanism for 0-RTT proxying, by communicating the relevant IP-addresses between the proxies. Thus, I don't think that we should specify the plain-mode option in the MPTCP working-group, as the same plain-mode option might be useful in any other transport-layer protocol. And we probably don't want a list of draft-sctp-plain-mode, draft-tcp-plain-mode, ...
