Oh, I see. On the RPi side, you don't have to talk to the RFM12B directly from the RPi using SPI -- you can use serial to talk to the uC, or you can get (or build) a device that has an USB port, and then connect the device (the gateway to 433 MHz) to the RPi using USB and talk to it through some serial communication protocol that you come up with. Felix apparently has the Moteino-USB, which comes with an USB interface.
