The specs say I *should* be able to read and write over SPI faster than a 1.77Mhz Z-80 can over its bus,

yea you should be able too, my 1024 led matrix uses SPI, and sends a 64 bit word out at ~780khz clock with a 8bit mcu only running at 16mhz

propeller runs quite a bit faster and its 32 bit isnt it?
