John,

I think this comment is a bit unfair. We had a session in Taipei where
this issue was discussed. The push for this is coming with support
from data center operators themselves, not from the VPN side (and the
"provider-provisioned" VPN side in particular, which is where both
L2VPN and L3VPN have historically worked from and what their current
charters continue to heavily emphasize is their starting point).

I think it has been established that while existing technologies could
be made to work in data centers in a *theoretical* sense, the Taipei
session showed that there were operators who are not entirely happy
with that approach and wanted the IETF to pursuse what we are
proposing.
