I am interested in I2C output for my own reasons. There's a good segment of the audiophile market that can post-process i2c and improve the audio significantly and produce an sp/dif output. So far, I don't have the full details for doing this but here is what I know to paraphrase hugo:

There is a 6 pin 2mm row of holes on the empeg board (not sure where) but it gives ground, 3.3v, i2c clock, i2c left, i2c right, i2c data1 and i2c data2 (front and rear). I'm mostly interested in the i2c format, but it's possible to use an sp/dif encoder (e.g. cirrus cs8405) and feed the sp/dif out an existing part of the harness, like the aux-in so you don't lose the docking convenience.

Hugo is the only person that knows the exact pin outs and location of that row of headers.

Comments?
