Semirelated: what's the easiest way of hooking up an I2C/SPI device to a PC? Given that most computers these days have about a dozen such buses in them, it should be easy --- but I'm not convinced about the wisdom of connecting random bits of dev hardware to critical peripheral buses.
Personally I'd use an AVR to drive it & forward stuff to its UART. Or the Obdev USB stack for AVR -- check out the USBasp programmer, that is effectively a "USB to SPI" adapter. I'm using that USB software a fair bit as I don't have a computer with a real UART (non-USB I mean) anymore... progress, eh.
There's also the USBprog to tinker with. Open Source drivers.
