Yes, I use this e.g. for my Alpine CD changer emulation, to hookup to a car
stereo. It doesn't require much speed.
The max. baudrate on the RX (remote) pin is 345600 Baud for a recorder,
Clk/32. The transmit would have to be done by bitbanging, which can also be quite
fast. We do similar for the LCD and get >800kHz.
It can be envisioned to tie multiple boxes together and form a kind of
network with it, collision detection like for ethernet.
