In case anyone is interested, I designed a simple board - an SPDIF to I2S or I2S to SPDIF converter. It's an open-hardware board and you can find the project here:

(Circuit Maker is the latest Altium's product - a free yet quite capable PCB software based on Altium Designer).
With a help of a few cables it can be easily powered from PINE headers and connected to PINE's I2S.
Feel free to produce/modify it in any way you wish.
It doesn't have an optical transmitter or receiver, but the board can be easily modified to contain such (instead of an RCA socket).
The original idea was to have a simple daughter board for a SigmaDSP motherboard (which, by the way is almost finished). By placing an SPDIF transceiver on a daughter board I will be able to easily customize the finished product (the motherboard contains ADAU1701 DSP, which has an ADC and a DAC and I use them both, so I don't even have to attach these daughter boards if I don't need digital input and output).
