Any idea of the price yet?

Price is not final, but it's looking like $40 each.

Would it be possible to get a panel mounting diagram, as well? The two holes and the square hole dimensions should suffice.

Cutout dimensions are 16.51 ± .25mm (.650 ± .010 in) across, and 13.95 ± 0.25mm (.535 ± .010in) vertically.

PDF for ethernet jack attached.

I will get a DXF file of the mounting pattern posted soon.

Is it possible to use just one module to achieve galvanic isolation for I2S ?

I2S input => teleporter => I2S output => Buffalo III DAC

No.

You would need TTL I2S input => teleporter(transmitter) => DIFFERENTIAL I2S => teleporter(receiver) => TTL I2S output => Buffalo III DAC

There would be no ground reference at the Buffalo end to use just one half of the differential signal. You could supply that from the source, but then, well, no isolation.

That and the LVDS signal level would be far too small.

Sorry, I do not quite understand all the technical details. For dummies:

If I just want to have galvanic isolation, I'd use IL715 chips as described here:
Which Digital Isolators for I2S? …or NOT H i F i D U I N O

If I want to have galvanic isolation plus the benefit of transmiitting the signal over longer wires, I'd use two of your Teleporter modules.

Question:
To have also galvanic isolation with two of your modules, would I need to cut/break the shielding (gnd) of the ethernet cable between the transmitting and receiving module ?

There is no ground in the ethernet connection, just four differential pairs.
