however, as janekm says, we can't charge just based on cost savings. We would need the router points to be sufficiently compelling wrt quality, speed and cost (including our own margins) that users still sometimes opt for these router points. Suffice it to say, if any router configs do start to take margins, then this will be clearly reflected in the overall router cost plotted on the scatter graph. UX will not be affected.
