In fact, a VGA port could be used as a very inexpensive high speed
digital to analog converter to achieve a multi-level encoding purely
in software... but then you do not have a matching recieve side.

The GNUradio board with the LF TX and LF RX board are pretty much
exactly what you'd need for building a multi-level encoded RONJA, but
it is not inexpensive.
