Jeff,
	I'm fuzzy on the definition of "service provider", but we bill the 
customer and provide support for a variety of services.  We do not own 
or manage the local FTTH network, it's owned and operated by the local 
power company.
	I _want_ to manage it, right at the demarc. Ideally i'd plug my switch 
into the FTTH CPE Switch and i'd rate-limit the ingress on my switch or 
the egress on my switch.  Ingress rate-limiting is my first choice, but 
egress policing would be better than nothing.
