This would be best managed by a very smart, but very simple piece of softwa=
re.
Just like Facebook or LinkedIn, or what-have-you, a network accepts a "peer=
/friend"
request from another network. Once both sides agree (and only as long as bo=
th sides
agree) the configuration is pinned up. Either side can pull it down. The co=
nfigs, up
to the hardware limits, would be pretty trivial.. Especially QinQ managemen=

uniqueness.
Not sure how switches handle HOL blocking with QinQ traffic across trunks, =
but hey...=20
what's the fun of running an IXP without testing some limits?
