Negative. There's no queueing mechanism to manage the order in which packets are processed - marking them won't do anything if the customer link is congested (assuming standard consumer cable/DSL). Home routers (that I've seen) can only effectively *reserve* bandwidth for an application which is not really desirable for most. Traffic shaping is the only real way to create a queue which can be managed (apart from TCP fiddling which is not available in consumer devices to my knowledge).
