I suspect that the OP is aware that BT Sport will be available on Youview via Infinity multicast come Aug 1st, but as he said, Infinity is not coming his way any time soon. The Youview box has no card slot, so BT Sport via DTT is obviously not an option.
The only possibility for the OP is if BT are planning on making BT Sport channels available on Youview via ADSL2+ in the future. We know they have set this up for the delivery of Sky Sports 1&2 to some existing customers with Vision+ boxes, but I'm not aware of any other announcements regarding that method of delivering live channels.
