Macetech’s Centipede Shield adds 64 IO pins to an Arduino. It’s got four Microchip MCP23017 I2C IO expanders, with I2C speeds up to 1.7MHz. Macetech will give you one if you’ve got a project that promotes the new hardware.
Thanks for the tip, also via Hack a Day.

experiment with Where are they available With a couple of Mcp23017 and mcp23s17 ic’s.and Approx. price
