Hi, all,

Can anyone give those of us not tracking 672 messages a brief summary?

IMO, without diving into that thread deeply, I agree with the new
proposed text below from Brian:

>    deleted or modified by any node along a packet's delivery path, until

In fact, I'd go further to say that that non-HBH EHs should not even be
*viewed* or used as context by intermediate nodes.

And any limits on what can be done with HBH EHs should be stated
explicitly. I'd be glad if at least the EH lengths didn't change.

Joe
