Hello,
I've read draft-hewu-mptcp-trust-00.Thanks for preparing this.
I have listed my comments below.

1: The idea for exchanging trusted addresses info for peers sounds
interesting, but i might want to see how the info will be used a bit more.
Say, if an endpoint has 1 trusted address and 2 non-trusted address, how
the endpoint utilizes these addresses?

2: I am wondering if the Trust-Flag in echo-backed ADD_ADDR can indicate
this source address is trusted. If so,  Host A in Figure 1 can update TPBT
after receiving ADD_ADDR from B.
If this is possible,  I am guessing we can reduce the cases where you need
to send ADDR_TRUST option.

Thanks,
--
