Arduino-Pi port programmer wanted

I am finishing up a general-purpose expansion backplane for Arduino projects. Includes RTC, EEPROM, MCP23017's, TFT display, etc. Most of the peripherals are driven by I2C and ICSP, using a Mega2560 as the controller. I have built an adapter card to seat a Rasberry PI instead of the Mega. Looking for someone to help port some of my library functions to the rPI.

I am thinking this should be straight forward (FamousLastWords), but I am not familiar with rPI development and I am running short of time. It might be a fun project for someone and I can supply some interesting hardware.
