I'm pretty sure a single A&A ADSL connection costs less than two from a bargain-basement ISP, what with line rental factoring into the total price.  Of course, not everyone is lucky enough to live in the UK and thus have access to A&A (myself included).

Something else to shoehorn into the Cake paper: as future work, an ISP-focused qdisc (or even a whole middlebox using commodity hardware) using a rearranged version of the technology proven in Cake.  Cake itself is focused on managing a single link, whereas an ISP must deal with many subscriber links (with a finite variety of service tiers) sharing a backhaul link, with the link interface hardware itself being unable to avoid bufferbloat or to share bandwidth fairly when congestion occurs.  The backhaul link might be to a local exchange, a shared cable medium, or a satellite hop.
