Well I have it working with some C code against my RPi-Zero from the above site:

Turns out it is 'not-quite' SPI in-as-much the chip select line is active high - normally CS is active low; not certain that the underlying py-spidev supports this, but at least it's some progress nonetheless.

I'm interested in adding support for Sharp Memory displays to luma.lcd, currently looking at the #63 code. Would such a contribution be interesting to upstream?
