Matt, The solution to the access link part of this problem is explained in: <http://tools.ietf.org/html/draft-briscoe-conex-initial-deploy-03#section-4.1.1> It can only distinguish access link congestion from shared congestion. Distinguishing home network congestion is harder, but possible with a tunnel to the home router, which already exists in some DSL arrangements (e.g. in BT we use a tunnel for services that share a line).
