I think the UFB rollout offers Sky an exceptional opportunity; imagine Sky becoming the cornerstone on-demand video delivery streaming service for the UFB network. With Sky's content rights library, a distribution network providing higher reliability (no rain-fade or end-of-life satellites to worry about), greater bandwidth for HD/4K channels and lower overall distribution costs, this could provide a killer app for the UFB network.
This would also be a significant draw-card for the UFB network, which has seen total connections of around 3%.
