OK, here's the rest. Usual caveats apply (thing I agreed with aren't
mentioned, etc).

I think those are more important for Traffic Engineering, no? I mean, if you
care _which_ ETRs traffic flow through, then you need those fields - but
caring which ETR traffic comes in through is by definition TE, no?

Well, the content is not actually repetitous, since the second one talks about
how TE is really functionally a routing thing. And I would have said that the
second is probably excess non-relevant detail, except that the para after that
goes on to talk about how doing TE with LISP is slightly 'hammer-nail', and I
think that needs the preceeding paragraph to make sense.

Well, you have a point about the thinness of what's said at the location of
the forward pointer, but alas I don't think I have a better place to point to
- details of applications of LISP are, for better or worse, outside the scope
of this document: to include them all would greatly increase the size of the
document. I have added a reference to the LISP-TE document.
And moving that content back here isn't really in the cards either: if I moved
all the content at forward references back, it would just create others. You
can't have 'everything in front of everything else'.

No, but it made me sad to take it out - the IETF is so humourless that it
can't tolerate a tiny bit of whimsy?

Well, I could have put in an allusion to that - except that that capability is
not mentioned until later. Again, everything before everything else
problems... :-(

It is pretty buzzwordy, but it's also pretty common - and also, I gather, one
of the most common uses of LISP in practise - so I had already added a bit
about it (although not that specific term - it just talks about "virtual
networks, and virtual machine mobility").

The problem is that the first thing one hears from a lot of people, when
talking about LISP, is 'oh, the caching won't work'. So I think we have to
talk about it.
I did earlier decide that this section was too long, with too much detail, and
so it has been reduced in size considerably,

I have tried to do this (as explained earlier), but I haven't recently done a
front-> back readthrough, and so I may have missed some. I will be doing such
a read-through 'soon' (as soon as I finish going through all the comments),
and I'll try and catch any remaining problems at that point. If anyone sees
any, of course, please let me know.

???? If I'm reading you correctly, out of 690 entries, ~20% are host entries?
How is this not "often"?
Not that it really matters - I can drop the "and often is" if it's an issue.

Dino mentioned this too. I dunno, the terminology _really_ confused me for a
while, and it took a while to get it straight. If people really don't like it,
I can remove it, though.
