The SPDIF can't carry 7.1 sound? It's just digital data stream. Should be able to carry how ever many channels get encoded to the data packets.
Is the problem not bandwidth requirements?
For consumer SPDIF max bandwidth is about 2 x 20 x 48 kHz = 1.92 Mbit/s.
E.g. encoded DD+ 7.1 bit stream fits there but linear 7.1 PCM doesn't. Highest end audio formats are at different order of magnitude. Dolby TrueHD can be up to 18 Mbit/s and DTS-HD Master Audio up to 24.5 Mbit/s those are passed only over HDMI in CE devices.
