[vnrg] way forward on VNRG definitions

[Joe Touch <touch at isi.edu>]

Hi, all,

(speaking as co-chair)

One of the challenges with starting with full text ("prose") is a tendency to
edit the text, to focus on what to change, rather than on either what's missing,
or shifts in perspective that would require substantial revision.

To avoid that, Martin and I propose that we begin by each providing definitions
and perspectives, rather than all try to wordsmith any single suggestion.

As a starting point, we would like to have everyone on the list answer the
following questions. We would prefer short text rather than full paragraphs
extracted from any I-D or other document.

Please DO NOT merely edit the posts of others. Once we see where people stand in
their own voice, we can decide how best to move forward.

Please send your responses by Jun 30 if possible.

-----------------------------------------------------

Starting questions:

1. how do you define VNs?

	1.a. what are the key components?

	1.b. what is the relationship between these components?

	1.c. what is the characteristic behavior/capability of the
	resulting system?

2. what are VNs used for?

3. what are they key challenges?

for each challenge:
	- define the challenge
	- explain why it is hard
	- provide some references to those working on solutions
