Finally have a preview version of the FastSPI_LED2 library up - some notes on it, and how to get it, here - http://waitingforbigo.com/2013/02/19/fastspi_led2_preview_release/ - it's still a bit rough around the edges, but i'm hoping to get those worked out over the next few weeks (with a diving trip in the middle there, where I will be more focused on sharks and coral reefs than leds and 'duino types). The performance on a teensy 3.0 at 24Mhz is pretty close to an arduino at 16Mhz. I'm hoping to do some more targeted tuning to squeeze more out of the teensy 3.0 as time goes on.
Also, this version of the library should work with most of the other teensy variants out of the box. Even if I don't have pin/port mappings set up for them, it should fall back to slightly slower, but fairly available, mechanisms for twiddling pins.
