If we don't consider those environments, I think we may be
under-estimating the size of current L2 deployments. The line between
service provider and enterprise is very blurry as the enterprise becomes
larger. I have run into quite a few larger enterprises that have
adopted a model where they provide services to the various
departments/divisions using a large L2 core, essentially becoming an
internal Metro Ethernet provider. Quite often, those are the
enterprises deploying the more advanced spanning tree technology as they
often see the "shortcomings" first.

Sounds like we have something to ask for in a liason statement :-) They
have given password access to the IETF before (you may just find it if
you look at http://www.ietf.org/proceedings/01aug/51-65.htm )
