Vach, Loa,

The L2VPN charter states
"The WG is responsible for standardization of the following solutions:
1. Virtual Private LAN Service (VPLS)--L2 service that emulates LAN
  across an IP and an MPLS-enabled IP network, allowing standard
  Ethernet devices communicate with each other as if they were
  connected to a common LAN segment.
...
"

This is the service that CE-based VPLS (where CE is provisioned by
provider) provides. I believe it does allow standard Ethernet devices to
communicate with each other as if they were connected to a common LAN
segment. So I think CE-based VPLS is within the scope of the L2VPN
charter (unless the charter is changed to explicitly exclude CE-based
VPLS). 

I believe the following drafts do not currently allow standard Ethernet
devices to communicate with each other as if they were connected to a
common LAN segment:
http://www.ietf.org/internet-drafts/draft-ietf-ppvpn-vpls-ldp-00.txt
http://www.ietf.org/internet-drafts/draft-ietf-ppvpn-vpls-bgp-00.txt
http://www.ietf.org/internet-drafts/draft-radoaca-ppvpn-gvpls-02.txt
http://www.ietf.org/internet-drafts/draft-shah-ppvpn-ipls-02.txt

I believe this draft does allow standard Ethernet devices to communicate
with each other as if they were connected to a common LAN segment:
