Hi Sabine, Thanks for the pointer. Yes, I think your proposal will meet the expectations of the sketched use cases. In fact, our proposal is orthogonal and tries to address the problem that in mobile networks, the network attachment point can be one additional important parameter that should be addressed in ALTO.
So far, ALTO helps to decide "where to connect to" (where: the endpoint that provides the service). The cost calendar enhances this to become "when and where to connect to". In mobile, the whole picture would become "via which cell/access, when and where to connect to".

Given that your draft poses the need for a calendar in its following sections 3.2.1. Cost calendar to extend battery life for background tasks and section 3.2.2. Cost calendar to optimize application sessions, you may want to look at http://tools.ietf.org/id/draft-randriamasy-alto-cost-calendar-02.txt, that proposes ALTO cost calendars and will be presented during the ALTO WG session as well, as it would be interesting to see how this proposal may meet your expectations. Best regards, Sabine
